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();
}
}
});
}
Manifest:
<application

Launcher activity not found

So I am redoing my app so that there will be an animation on the start screen of the app. The only problem is it seems you cannot start an app with a view class. At least I'm not really sure if you can. Here is my code. With this code i get a launcher activity not found in the console?
public class SplashLaunch extends Activity{
#Override
protected void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
this.requestWindowFeature(Window.FEATURE_NO_TITLE);
this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,WindowManager.LayoutParams.FLAG_FULLSCREEN);
setContentView(R.layout.splashlaunch);
final Main d = new Main(this);
new Handler().postDelayed(new Runnable() {
#Override
public void run() {
setContentView(d);
}
}, 5000);
}
}
Here is the manifest file. I have a feeling that I'm going to need to change this.
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.Tripps.thesimplegame"

Likely somewhere in your launcher activity you have an onCreate method:
public class YourActivity extends Activity {
#Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.foobar);
}
}
Just change the setContentView to your custom view:
public class YourActivity extends Activity {
#Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
MyCustomView view = new MyCustomView(this);
setContentView(view);
}
}

The Activity that you want to start when the app first starts MUST have the following Intent filter:
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>

Try to resolve ActivityNotFoundException

I try to share a post on google+ but I obtain this Exception. The Activity that creates the Exception is ExampleActivity and this is its code:
public class ExampleActivity extends Activity implements OnClickListener,
ConnectionCallbacks, OnConnectionFailedListener {
private static final String TAG = "ExampleActivity";
private static final int REQUEST_CODE_RESOLVE_ERR = 9000;
private ProgressDialog mConnectionProgressDialog;
private PlusClient mPlusClient;
private ConnectionResult mConnectionResult;
#Override//onCreate
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_example);
mPlusClient = new PlusClient.Builder(this, this, this)
.setVisibleActivities("http://schemas.google.com/AddActivity","http://schemas.google.com/BuyActivity")
.build();
// Progress bar to be displayed if the connection failure is not resolved.
mConnectionProgressDialog = new ProgressDialog(this);
mConnectionProgressDialog.setMessage("Signing in...");
Button shareButton = (Button) findViewById(R.id.share_button);
shareButton.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// Launch the Google+ share dialog with attribution to your app.
Intent shareIntent = new PlusShare.Builder()

.getIntent();
startActivityForResult(shareIntent, 0);
}
});
}
#Override//onStart

super.onStart();
mPlusClient.connect();
}
#Override//onStop

mPlusClient.disconnect();
}
#Override// onConnectionFailed
public void onConnectionFailed(ConnectionResult result) {

if (result.hasResolution()) {
try {
result.startResolutionForResult(this, REQUEST_CODE_RESOLVE_ERR);
} catch (SendIntentException e) {
mPlusClient.connect();
}
}
}
// Save the result and resolve the connection failure upon a user click.
mConnectionResult = result;
}
#Override //onActivityResult
protected void onActivityResult(int requestCode, int responseCode, Intent intent) {

Someone can help me?

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

Intent using thread is not working

I know I already asked this, but I didn't get a sufficient answer. Im trying to start an activity, but the emulator stays on the first activity. Ive tried all ways to do it but it never works. The youtube videos show that it should work but it never does. Is there something missing or is there anything wrong with the following code?
//First Activity:
package com.mtprogramming.magicsquaresgame;
import android.os.Bundle;
import android.app.Activity;
import android.view.Menu;
import android.content.Intent;
public class Opening extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_opening);
Thread timer = new Thread(){
public void run(){
try{
sleep(5000);
} catch (InterruptedException e) {
e.printStackTrace();
}finally{
Intent open = new Intent("com.mtprogramming.magicsquaresgame.MENU");
startActivity(open);
}
}
};
timer.start();
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.opening, menu);
return true;
}
}
//Second Activity:
package com.mtprogramming.magicsquaresgame;
import android.app.Activity;
import android.os.Bundle;
//Created by suprav on 7/11/13.
public class Menu extends Activity {
public void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_menu);
}
}
//Android Manifest:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.mtprogramming.magicsquaresgame"
android:versionCode="1"
android:versionName="1.0" >

android:minSdkVersion="7"
android:targetSdkVersion="17" />
<application
android:allowBackup="true"
android:icon="#drawable/ic_launcher"

<activity
android:name="com.mtprogramming.magicsquaresgame.Opening"
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="com.mtprogramming.magicsquaresgame.Menu"
android:label="#string/title_activity_menu"
android:parentActivityName="Opening" >
<intent-filter>
<action android:name="com.mtprogramming.magicsquaresgame.MENU"/>
<category android:name="android.intent.category.DEFAULT"/>
</intent-filter>
<meta-data
android:name="android.support.PARENT_ACTIVITY"
android:value="Opening" />
</activity>
</application>
</manifest>

Try this:
Intent open = new Intent(Opening.this, Menu.class);
startActivity(open);

I think i found the issue, seems like metadata property is not being properly used, hences activity its not being started, this is the proper way to use the property:
<activity android:name=".TestActivity" >
<meta-data android:name="android.support.PARENT_ACTIVITY"
android:value=".TestParentActivity">
</meta-data>
</activity>
So, seems like you are missing a dot in "android:value="Opening"
Regards!

Splash Screen will not display

I am trying to implement a Splash Screen using this java and xml code. I created a separate java class from my main activity and placed the java code inside. I created an xml layout in my layout file and placed the xml code inside. However, my app appears normally without a splash screen. It never shows, but the app does not have any errors. Eclipse is not showing any errors either. What could be the cause to this? Thank you in advance. Here is the code.
Java:
package com.carouseldemo.main;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.os.Handler;
import android.view.Menu;
public class Splash extends Activity {
private final int SPLASH_DISPLAY_LENGHT = 1000;
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle icicle) {
super.onCreate(icicle);
setContentView(R.layout.splash);
/* New Handler to start the Menu-Activity
* and close this Splash-Screen after some seconds.*/
new Handler().postDelayed(new Runnable(){
#Override
public void run() {
/* Create an Intent that will start the Menu-Activity. */
Intent mainIntent = new Intent(Splash.this,Menu.class);
Splash.this.startActivity(mainIntent);
Splash.this.finish();
}
}, SPLASH_DISPLAY_LENGHT);
}
}
XML:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="fill_parent"
android:layout_height="fill_parent">
<ImageView android:id="#+id/splashscreen" android:layout_width="wrap_content"
android:layout_height="fill_parent" android:src="#drawable/cat"
android:layout_gravity="center"/>
<TextView android:layout_width="fill_parent"
android:layout_height="wrap_content" android:text="Hello World, splash"/>
</LinearLayout>
Manifest:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.carouseldemo.main"
android:versionCode="1"
android:versionName="1.0"
>
<uses-sdk android:minSdkVersion="8" android:targetSdkVersion="17" android:screenOrientation="portrait"/>
<application android:icon="#drawable/buttonone" android:label="#string/app_name">
<activity android:name=".MainActivity" android:label="#string/app_name" android:screenOrientation="portrait" android:configChanges="orientation|keyboardHidden" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>

MainActivity is launcher activity in manifest file. So, splash is not showing.
Change the launcher activity MainActivity to Splash and write another for MainActivity.
<application android:icon="#drawable/buttonone" android:label="#string/app_name">
<activity android:name=".Splash" android:label="#string/app_name" android:screenOrientation="portrait" android:configChanges="orientation|keyboardHidden" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity android:name=".MainActivity" />
</application>

Replace the Handler part with this :
Thread splashThread = new Thread() {
public void run() {
try {
Thread.sleep(SPLASH_DISPLAY_LENGHT);
} catch (Exception e) {
} finally {
Intent i = new Intent(Splash.this,Menu.class);
startActivity(i);
finish();
}
}
};
splashThread.start();

private static final int STOPSPLASH = 0;
private static final long SPLASHTIME =3000;
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
setContentView(R.layout.splash);
context = getApplicationContext();
if(savedInstanceState == null){
Message msg = new Message();
msg.what = STOPSPLASH;
spHandler.sendMessageDelayed(msg, SPLASHTIME);
}
}
private Handler spHandler = new Handler() {
#Override
public void handleMessage(Message msg)
{
switch (msg.what)
{
case STOPSPLASH:
gotoHomeScreen();
break;
default:
break;
}
super.handleMessage(msg);
}
};
public void gotoHomeScreen(){
Intent i = new Intent();
i.setClass(Splash.this,Home.class);
startActivity(i);
finish();
spHandler = null;
}
try this.
in your manifest
<activity android:name="Splash" android:configChanges="keyboardHidden" android:theme="#android:style/Theme.NoTitleBar">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>

Try out as below :
public class Splash extends Activity
{
private final int SPLASH_DISPLAY_LENGHT = 1000;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.splash);
new Thread(){
public void run()
{
try
{
sleep(SPLASH_DISPLAY_LENGHT);
Intent mainIntent = new Intent(Splash.this,Menu.class);
Splash.this.startActivity(mainIntent);
Splash.this.finish();
}
catch (InterruptedException e)
{
e.printStackTrace();
}
};
}.start();
}
EDITED:
<activity android:name=".Splash" android:label="#string/app_name" android:screenOrientation="portrait" android:configChanges="orientation|keyboardHidden" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>

Another way to achieve using CountDownTimer
public class MyCounter extends CountDownTimer {
public MyCounter(long millisInFuture, long countDownInterval) {
super(millisInFuture, countDownInterval);
}
#Override
public void onFinish() {
startActivity(new Intent(SplashScreen.this,
TabSample.class));
finish();
MCObject.cancel();
}
#Override
public void onTick(long millisUntilFinished) {
}
}
Within OnCreate
MyCounter MCObject;
MCObject = new MyCounter(3000, 100);
MCObject.start();

Use this code, it might help you.
public class SplashScreenActivity extends Activity {
protected int _splashTime = 2000;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_splash_screen);
Thread splashTread = new Thread() {
#Override
public void run() {
try {
sleep(_splashTime);
}
} catch (InterruptedException e) {
// do nothing
} finally {
startActivity(new Intent(SplashScreenActivity.this,
MainActivity.class));
SplashScreenActivity.this.finish();
}
}
};
splashTread.start();
}
Hope it will help you.

Replace your handler
new Thread(new Runnable() {
public void run() {
try {
Thread.sleep(SPLASH_TIME);
startActivity(intent);
finish();
} catch (InterruptedException e) {
e.printStackTrace();
}
}
}).start();
