how do I get value from BroadcastReceiver activity to main activity - java

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);
}
}

This was i implemented in my project. its working for me. Use this code
(1) MainActivity.java
public class MainActivity extends Activity {
TextView tv1;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
tv1 = (TextView) findViewById(R.id.tv1);
}
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).
edit().putString("referrer", referrer).commit();
}
} 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) {
//Toast.makeText(context, "ReferrerReceiver catch"+e, Toast.LENGTH_LONG).show();
MainActivity.log(context, e.toString());
}
}
}

(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.

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"?>

<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

Can't send push to android using GCM

Sorry for my english. I have spent 2 days but I can't send push messages to android. I use google cloud message. For example in gcm I create a new project and I have an id:
Then I enabled gcm and added the server key
I have code like this:

I use service and tried to send some push messages to the device. In service it says Success. But the push in android is not coming (I have no output in the log)
I assume your app package name must be com.example.alexy.gcmclient or replace the package name build.gradle
defaultConfig
applicationId "com.yourpackge"
<permission
android:name="com.example.alexy.gcmclient.permission.C2D_MESSAGE"
android:protectionLevel="signature" />
<uses-permission
android:name="com.example.alexy.gcmclient.permission.C2D_MESSAGE" />
<receiver android:name=".GcmBroadcastReceiver"
android:permission="com.google.android.c2dm.permission.SEND" >
<intent-filter>
<action android:name="com.google.android.c2dm.intent.REGISTRATION" />
<action android:name="com.google.android.c2dm.intent.RECEIVE" />
<category android:name="com.example.alexy.gcmclient" />
</intent-filter>
</receiver>
The package names for C2D_MESSAGE are wrong, change them to your package name. Also, make sure you have the configuration file near the build.gradle of your app directory. Edit: go through all of the manifest and change wherever you see hmk to your package name. Your package name should be com.example.alexy.gcmclient as per your manifest.

Try and clean the project, uninstall your app from device and reinstall.

You have registered your broadcast receiver with the string "RECEIVE_SMS". The IntentFilter should be of a form of an action. With your declaration:
static final String ACTION = "android.provider.Telephony.SMS_RECEIVED";
you will have:
registerReceiver(new BroadcastReceiver() {
#Override
public void onReceive(Context context, Intent intent) {
Log.i(LOG_TAG, "onReceive");
}
}, new IntentFilter(ACTION));
You can have a look at the Api demos Manifest for the XML declaration
You can't use receiver as an inner class. Create a separate one.
Don't you need to specify that you want to receive SMS in your manifest?
<application android:icon="#drawable/icon" android:label="#string/app_name">
<receiver android:name=".MyApp">
<intent-filter>
<action android:name="android.provider.Telephony.SMS_RECEIVED" />
</intent-filter>

ERROR/dalvikvm(1399): Could not find class 'maptest.xyz.com.maps', referenced from method maptest.xyz.com.maptest$1.onClick

The problem is that if i use these two lines of code,my app closes unxepectedly and if not used, the app works just fine...is there any other way to get to the maps.class?
The following is the code i used:
Intent in = new Intent(BlobCity.this, maps.class)
startActivity(in);
the following is my manifest file:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"

maps.java:
import android.os.Bundle;

import com.google.android.maps.MapView;
public class maps extends MapActivity{

/** Called when the activity is first created. */

#Override
protected boolean isRouteDisplayed() {
// TODO Auto-generated method stub
return false;
}
}
Your tag <uses-library android:name="com.google.android.maps" /> has to be inside the <application> tag!
manifest has to be like this:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="BlobCity.xyz.com"
android:versionCode="1"
android:versionName="1.0">
<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>
<application android:icon="#drawable/icon" android:label="#string/app_name">
**<uses-library android:name="com.google.android.maps" />**
<activity android:name=".BlobCity"
android:label="#string/app_name">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity android:name=".maps" />
</application>
</manifest>
Try:
Intent in = new Intent(BlobCity.this.getApplicationContext(), maps.class)
startActivity(in);
Activity (Class) name must start with capital letter, and instead of using BlobCity.this use only "this" keyword which refers the Context of the current Activity
e.g.
Intent in = new Intent(this, Maps.class)
startActivity(in);
also make sure entry of this Activity must be in your AndroidManifest.xml file
e.g.
<activity android:name=".Maps"></activity>
