Avoiding running an Android application twice, from Eclipse to a real device

Question

I launch the application from eclipse and run it twice: first I launch the application and then restart again after a few seconds

My application Popup --- → Main action (Both open twice).

I already tried adding android: launchMode = "singleInstance" to my manifest file, but did not succeed.

I tried 3 different applications from my eclipse still opening twice in my Kitkat, Lollipop real device (created a new project that also opens twice)

EDIT 1:

I tried adding this line to the manifest file, but not Success- android: launchMode = "singleTop"

Please let me know how to solve this problem.

manifest file:

<application android:allowBackup="true" android:icon="@drawable/logo" android:label="@string/app_name" android:largeHeap="true" android:launchMode="singleInstance" android:theme="@style/AppTheme2" > <activity android:name=".Start" android:label="@string/app_name" android:screenOrientation="portrait" > <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity> <activity android:name=".MainActivity" android:screenOrientation="portrait" > <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.DEFAULT" /> </intent-filter> </activity> </application> 

My launch of Activity.java

 public class Start extends Activity { SessionManagerFor_Signin session; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); // Session class instance session = new SessionManagerFor_Signin(getApplicationContext()); // Remove the Title Bar requestWindowFeature(Window.FEATURE_NO_TITLE); setContentView(R.layout.start); ImageView Image1=(ImageView)findViewById(R.id.imageView1); //Animation Bottom to Top TranslateAnimation animation2 = new TranslateAnimation(0.0f, 0.0f,400.0f, 0.0f); animation2.setDuration(1000); animation2.setFillAfter(false); Image1.startAnimation(animation2); Thread timer = new Thread() { @Override public void run() { try { sleep(3000); } catch (InterruptedException e) { e.printStackTrace(); } finally { session.checkLogin(); finish(); } } }; timer.start(); //For Full Action bar Color Starts if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) { setTranslucentStatus(true); } SystemBarTintManager tintManager = new SystemBarTintManager(this); tintManager.setStatusBarTintEnabled(true); tintManager.setStatusBarTintResource(R.color.FUllStartColor); //For Full Action bar Color Ends here } @TargetApi(19) private void setTranslucentStatus(boolean on) { Window win = getWindow(); WindowManager.LayoutParams winParams = win.getAttributes(); final int bits = WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS; if (on) { winParams.flags |= bits; } else { winParams.flags &= ~bits; } win.setAttributes(winParams); } 

Answer 1

Remove this from one of two actions:

  <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> 

This intent filter points to Android, which is the main activity, and you should only have one.

Answer 2

Apply the intent filter in only one of your actions. Remove from MainActivity ...

 <application android:allowBackup="true" android:icon="@drawable/logo" android:label="@string/app_name" android:largeHeap="true" android:launchMode="singleInstance" android:theme="@style/AppTheme2" > <activity android:name=".Start" android:label="@string/app_name" android:screenOrientation="portrait" > <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity> <activity android:name=".MainActivity" android:screenOrientation="portrait" > </activity> </application> 

Answer 3

try the following:

 android:launchMode="singleTask" 

Maybe it will work. If it does not work, reinstall eclipse.

Answer 4

Apply below to the activity of your splash screen, then clean the project and run it again.

Try to register activity in the manifest file with the full package name.

 <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> 

Answer 5

Try adding launchmode "singleTop" to your activity in your manifest.

 <activity android:name="MyActivity" android:launchMode="singleTop" ... >
