my code is working fine but its only open the app from it's package name, it's not opening activity.

Code:

public void startApplication(String packageName) { try { Intent intent = new Intent("android.intent.action.MAIN"); intent.addCategory("android.intent.category.LAUNCHER"); intent.addFlags(Intent.FLAG_ACTIVITY_NO_ANIMATION); List<ResolveInfo> resolveInfoList = getPackageManager().queryIntentActivities(intent, 0); for(ResolveInfo info : resolveInfoList) if(info.activityInfo.packageName.equalsIgnoreCase(packageName)) { launchComponent(info.activityInfo.packageName, info.activityInfo.name); return; } // No match, so application is not installed showInMarket(packageName); } catch (Exception e) { showInMarket(packageName); } } private void launchComponent(String packageName, String name) { Intent intent = new Intent("android.intent.action.MAIN"); intent.addCategory("android.intent.category.LAUNCHER"); intent.setComponent(new ComponentName(packageName, name)); intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK); startActivity(intent); } private void showInMarket(String packageName) { Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse("market://details?id=" + packageName)); intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK); startActivity(intent); }
