Unable to open a package(module) inside another package using a button

I have imported a package which was downloaded from the link "https://github.com/moritz-wundke/android-page-curl", then I created a new project and imported the downloaded package by clicking on "import module". I have added a button inside my new package to open the downloaded package. But its not working. Can someone help. Here is the code
public class MainActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button button = (Button)findViewById(R.id.button);
button.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent i;
PackageManager manager = getPackageManager();
try {
i = manager.getLaunchIntentForPackage
("fi.harism.curl");
if (i == null)
throw new PackageManager.NameNotFoundException();
i.addCategory(Intent.CATEGORY_LAUNCHER);
startActivity(i);
} catch (PackageManager.NameNotFoundException e) {
e.printStackTrace();
}
}
});
}

Android app in background

I have to create application and want to use it always when phone works, currently my code is:
Android Manifest:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.plan.pedometer">
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
<application
android:allowBackup="true"
android:icon="#mipmap/ic_launcher"
android:label="#string/app_name"
android:supportsRtl="true"
android:theme="#style/AppTheme">
<activity
android:name=".MainActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<service android:enabled="true"
android:name=".PedometerService"/>
<receiver
android:name=".receiver.StartPedometerServiceAtBootReceiver"
android:label="StartPedometerServiceAtBootReceiver">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
</intent-filter>
</receiver>
</application>
</manifest>
StartPedometerServiceAtBootReceiver:
public class StartPedometerServiceAtBootReceiver extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
if (Intent.ACTION_BOOT_COMPLETED.equals(intent.getAction())) {
Intent serviceIntent = new Intent(context, PedometerService.class);
context.startService(serviceIntent);
}
}
}
Service:
public class PedometerService extends IntentService {
private int Steps=0;
public PedometerService() {
super("Pedometer_Worker_Thread");
}
#Override
protected void onHandleIntent(Intent intent) {
putInSharedPreferences();
synchronized (this) {
try {
wait(1000000);
} catch (InterruptedException e) {
e.printStackTrace();
}
}
}
public void putInSharedPreferences(){
stepsNumbers = getApplicationContext().getSharedPreferences("stepsData", MODE_PRIVATE);
editorStepsNumbers=stepsNumbers.edit();
editorStepsNumbers.putInt(String.valueOf(STEPS),Steps).apply();
}
}
It works if I start Service in MainActivity by:
Intent intent = new Intent(getApplication(),PedometerService.class);
startService(intent);
and Service is running in background but when I restart my phone nothing happens and Service does not start.
I have one more question, this is Pedometer application, where should I put onSensorChange method in Service? Create something like while(1) in onHandleIntent() and put it there?
UPDATE - my actually code is:
I followed this tutorial https://github.com/codepath/android_guides/wiki/Starting-Background-Services
and tried to use WakefulBroadcastReceiver
AndroidManifest:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"

<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
</intent-filter>
</receiver>
</application>
</manifest>
MainActivity:
public class MainActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
#Override
protected void onStart() {
super.onStart();
launchTestService();
}
public void launchTestService() {
// Construct our Intent specifying the Service
Intent i = new Intent(this, MyTestService.class);
// Add extras to the bundle
i.putExtra("foo", "bar");
// Start the service
startService(i);
}
}
Receiver:
public class BootBroadcastReceiver extends WakefulBroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
// Launch the specified service when this message is received
Intent startServiceIntent = new Intent(context, MyTestService.class);
startWakefulService(context, startServiceIntent);
}
}
Service:
public class MyTestService extends IntentService {
Handler handler;
// Must create a default constructor
public MyTestService() {
// Used to name the worker thread, important only for debugging.
super("test-service");
}
#Override
public void onCreate() {
super.onCreate(); // if you override onCreate(), make sure to call super().
// If a Context object is needed, call getApplicationContext() here.
handler = new Handler();
}
#Override
protected void onHandleIntent(Intent intent) {
WakefulBroadcastReceiver.completeWakefulIntent(intent);
handler.post(new Runnable() {
#Override
public void run() {
Toast.makeText(MyTestService.this, "start", Toast.LENGTH_LONG).show();
int i = 0;
}
});
int i=0;
while(true){
i++;
// Do some work here
if(i>1000)
i=0;
}
}
#Override
public void onDestroy() {
super.onDestroy();
Toast.makeText(MyTestService.this, "stop", Toast.LENGTH_SHORT).show();
}
}
I used while(true) in MyTestService for check that app is running in background, in project I will use sensors (this is pedometer application) then I want to put something like MyAlarmReceiver from tutorial to send data to the server several times a day.

try this

I have tested when application started service will be start , even if your application destroyed service will be started again.Even if reboot android device service will be started.
Second question :
if you will use sensor with service you need to register sensor listener and unregister sensor listener when service destroyed,oncreate method override sensor object and create sensor and sensor manager.In onstartCommand method register generated sensor listener sensor manager object ,unregister listener when service destroy
you can check this link
Accelemeter in android
if you want to send message from service to activity,you have to implement onbind() method ,activity need to bind on service check this link
bind activity on service using sensor
bind/unbind service

Android fatal exception unable to resume activity

Hi everybodi!
I'm new to Android programming and am trying to create a QR code reader app with Zxing. When I start my application in my phone, it gives me this error message. The app is started, after I push the button and then this is thrown... What is the problem?
Here is my code: This is the MainActivity
package com.example;
public class MainActivity extends Activity {
private Button scan;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
scan= (Button)findViewById(R.id.button1);
scan.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
Intent intent = new Intent("com.google.zxing.client.android.SCAN");
intent.putExtra("SCAN_MODE", "QR_CODE_MODE");
startActivityForResult(intent, 0);
}
});
}
public void onActivityResult(int requestCode, int resultCode, Intent intent) {
if (requestCode == 0) {
if (resultCode == RESULT_OK) {
String contents = intent.getStringExtra("SCAN_RESULT");
String format = intent.getStringExtra("SCAN_RESULT_FORMAT");
// Handle successful scan
} else if (resultCode == RESULT_CANCELED) {
// Handle cancel
Log.i("App","Scan unsuccessful");
}
}
}
#Override

how do I get value from BroadcastReceiver activity to main activity

I want get the install referrer value in my MainActivity. For that i am using two class
1) MainActivity
2) ReferrerReceiver
I got received install referrer value successfully in ReferrerReceiver class, i tested this using Toast control.
But i can not able to pass this value to MainActivity from ReferrerReceiver.
Bellow is i tried code. please any one help me.
Thanks for advance.
1) MainActivity.java
public class MainActivity extends Activity {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
TextView tv1 = (TextView) findViewById(R.id.tv1);
Intent in1= getIntent();
String ldString = in1.getStringExtra("number");
tv1.setText(ldString);
}
}
2) ReferrerReceiver.java
public class ReferrerReceiver extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
if (!intent.getAction().equals("com.android.vending.INSTALL_REFERRER")) {
return;
}
Bundle bundle = intent.getExtras();
String phoneNumber = bundle.getString("referrer");
Intent i = new Intent(context, MainActivity.class);
i.putExtra("number", phoneNumber);
context.startActivity(i);

}
public static void log(Context context, String string) {
if(string!=null) {
Toast.makeText(conte, "Referrer value is."+string, Toast.LENGTH_LONG).show();
tv1.setText(string);
}
}
(2) ReferrerReceiver.java
public class ReferrerReceiver extends BroadcastReceiver {
String referrer,rawReferrer;
public static String getReferrer(Context context) {
// Return any persisted referrer value or null if we don't have a referrer.
return context.getSharedPreferences("referrer", Context.MODE_PRIVATE).getString("referrer", null);
}
#Override
public void onReceive(Context context, Intent intent) {
try {
// Make sure this is the intent we expect - it always should be.
if ((null != intent) && (intent.getAction().equals("com.android.vending.INSTALL_REFERRER"))) {
// This intent should have a referrer string attached to it.
rawReferrer = intent.getStringExtra("referrer");
if (null != rawReferrer) {
// The string is usually URL Encoded, so we need to decode it.
referrer = URLDecoder.decode(rawReferrer, "UTF-8");
Toast.makeText(context, "ReferrerReceiver." + referrer, Toast.LENGTH_LONG).show();
MainActivity.log(context,"\nRaw referrer: " + rawReferrer +"\nReferrer: " + referrer);
MainActivity.log(context,referrer);
// Persist the referrer string.
context.getSharedPreferences("referrer", Context.MODE_PRIVATE).
edit().putString("referrer", referrer).commit();
} else {
Toast.makeText(context, "ReferrerReceiver." + referrer, Toast.LENGTH_LONG).show();
MainActivity.log(context,referrer);
context.getSharedPreferences("referrer", Context.MODE_PRIVATE).

}
} else {
Toast.makeText(context, "ReferrerReceiver intent value is null.", Toast.LENGTH_LONG).show();
MainActivity.log(context,referrer);
MainActivity.log(context,"intent value is nulll");
context.getSharedPreferences("referrer", Context.MODE_PRIVATE).
edit().putString("referrer", "intent value is nulll").commit();
}
}
catch (Exception e) {

(4) sample link:
https://play.google.com/store/apps/details?id=your_package_name&referrer=Welcome

You are using
Intent in1 = new Intent();
String ldString = in1.getStringExtra("KEY");
you are declaring new intent which is wrong, and also key you put is also wrong, which should be number
Replace it With,
Intent intent= getIntent();
String ldString = intent.getStringExtra("number");

you have declared your activity as"single Task" in Manifest;so if an instance of your
activity is already launched the system will create (NewIntent) to re_lunch your
activity.try to put this code before onCreate():
#Override
protected void onNewIntent(Intent intent) {
super.onNewIntent(intent);
// NOW getIntent() should always return the recent
setIntent(intent);
}
to get all the time the newest intent with the new extras.

And here are the .java files of my .Splash activity and my .Menu activity:
Splash
package com.example.secondapp;
import android.app.Activity;
import android.content.Intent;
import android.media.MediaPlayer;
import android.os.Bundle;
public class Splash extends Activity {
MediaPlayer ourSong;
#Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.splash);
ourSong = MediaPlayer.create(Splash.this, R.raw.happyman);
ourSong.start();
Thread timer = new Thread(){
public void run(){
try{
sleep(5000);
} catch (InterruptedException e){
e.printStackTrace();
}finally{
Intent startMain = new Intent("com.example.secondapp.MENU");
startActivity(startMain);
}
}
};
timer.start();
}
#Override
protected void onPause() {
// TODO Auto-generated method stub
super.onPause();
finish();
}
}
Menu
package com.example.secondapp;
public class Menu extends ListActivity {
String classes[] = {"MainActivity", "example1", "example2", "example3", "example4", "example5"};
#Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setListAdapter(new ArrayAdapter<String>(Menu.this, android.R.layout.simple_list_item_1, classes));
}
#Override
protected void onListItemClick(ListView l, View v, int position, long id) {
// TODO Auto-generated method stub
String Cheese = classes[position];
super.onListItemClick(l, v, position, id);
try{
Class ourClass = Class.forName("com.example.secondapp." + Cheese);
Intent ourIntent = new Intent(Menu.this, ourClass);
startActivity(ourIntent);
}catch(ClassNotFoundException e){
e.printStackTrace();
}
}
}

in your manifest the action should match. Change it with com.example.secondapp.MENU

It is in caps MENU should be Menu
Change to
Intent startMain = new Intent("com.example.secondapp.Menu");
coz your activity is public class Menu extends ListActivity { and in manifest you have
<activity
android:name=".Menu"
Edit:
Explicit intents designate the target component by its name (the
component name field, mentioned earlier, has a value set). Since
component names would generally not be known to developers of other
applications, explicit intents are typically used for
application-internal messages — such as an activity starting a
subordinate service or launching a sister activity.
Implicit intents do not name a target (the field for the component
name is blank). Implicit intents are often used to activate
components in other applications.
So Change to explicit intent
Intent startMain = new Intent(Splash.this,Menu.class); // in Splash.java
and in manifest
<activity
android:name="com.example.secondapp.Menu"
android:label="#string/app_name" >
</activity>
For more info check the docs
http://developer.android.com/guide/components/intents-filters.html

You need to set activity class in your manifest and you misspelled MENU
replace
<activity
android:name=".Menu"
android:label="#string/app_name" >
with
<activity
android:name=".MENU"
android:label="#string/app_name" >
