Don't do that within your java code. Simply remove this tags from your manifest:

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

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

These tags are in your first activity tags in your manifest.

can you help me ? – android developer Dec 14 '16 at 10:15
Look at your comments, you said that you aren't using android studio, then you said you are using it!!! If you are using android studio, then you should have a manifest file! – A. Badakhshan Dec 14 '16 at 10:19
i said my project can't run in android studio when i used your code,finally i use build item in android studio for deploying apk file and app didn't run android devices – android developer Dec 14 '16 at 10:24
Its because this way you won't have an starting activity. Your app will just install on the device. After that you can call your activity from another app like you want. – A. Badakhshan Dec 14 '16 at 10:42
is it true this code? Intent intent = new Intent(Intent.ACTION_MAIN); intent.addCategory(Intent.CATEGORY_LAUNCHER); intent.setComponent(new ComponentName(txt_package_name,txt_package_name+".MainActivity")); intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK); startActivity(intent); – android developer Dec 14 '16 at 10:59
