I start a new <code>Activity B</code> from within my <code>MainActivity</code> with </p> <pre><code>Intent mIntent = new Intent(this, ActivityB.class); mIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK); //tried addFlags as well startActivity(mIntent); </code></pre> <p>Suddenly (between 10-45seconds), suddenly the <code>MainActivity</code> is starting again, without any reason. In Logcat, I see that the <code>MainActivity</code> is being created again (not even resumed), and received the intent <code>android.intent.action.MAIN</code></p> <p>Even more weird is, if I start another <code>ActivityC</code>, in the same way, it's working fine and not jumping back to the MainActivity...</p> <p>Anyone any ideas?</p> <p>Logcat</p> <pre><code>05-21 15:35:13.897: D/dalvikvm(14312): GC_FOR_ALLOC freed 8K, 6% free 18231K/19356K, paused 33ms, total 33ms 05-21 15:35:13.936: D/dalvikvm(14312): GC_CONCURRENT freed 17K, 6% free 18213K/19356K, paused 2ms+5ms, total 33ms 05-21 15:35:14.108: D/dalvikvm(14312): GC_FOR_ALLOC freed 71K, 6% free 18235K/19356K, paused 25ms, total 26ms 05-21 15:35:14.123: I/dalvikvm-heap(14312): Grow heap (frag case) to 27.696MB for 10342416-byte allocation 05-21 15:35:14.155: D/dalvikvm(14312): GC_FOR_ALLOC freed 0K, 4% free 28335K/29460K, paused 24ms, total 24ms 05-21 15:35:14.178: D/dalvikvm(14312): GC_CONCURRENT freed 1K, 4% free 28334K/29460K, paused 3ms+5ms, total 28ms 05-21 15:35:14.780: I/Choreographer(14312): Skipped 58 frames!
