Answer 1

try this :

Intent launchIntent = new Intent(Intent.ACTION_MAIN).addCategory(
launchIntent.CATEGORY_LAUNCHER).setClassName("com.ittipon.test",
"com.ittipon.test.YOUR_ACTIVITY_NAME").addFlags(Intent.FLAG_ACTIVITY_NEW_TASK)
.addFlags(Intent.FLAG_FROM_BACKGROUND).setComponent(new ComponentName("com.ittipon.test",
"com.ittipon.test.YOUR_ACTIVITY_NAME"));
this.startActivity(launchIntent);

or

Intent launchIntent = getPackageManager().
getLaunchIntentForPackage("com.ittipon.test");    
startActivity(launchIntent);
