public void openInbox() {
String application_name = "com.android.mms";
try {
Intent intent = new Intent("android.intent.action.MAIN");
intent.addCategory("android.intent.category.LAUNCHER");

intent.addFlags(Intent.FLAG_ACTIVITY_NO_ANIMATION);
List<ResolveInfo> resolveinfo_list = this.getPackageManager()
.queryIntentActivities(intent, 0);

for (ResolveInfo info : resolveinfo_list) {
if (info.activityInfo.packageName
.equalsIgnoreCase(application_name)) {
launchComponent(info.activityInfo.packageName,
info.activityInfo.name);
break;
}
}
} catch (ActivityNotFoundException e) {
Toast.makeText(
this.getApplicationContext(),
"There was a problem loading the application: "
+ application_name, Toast.LENGTH_SHORT).show();
}
}

private void launchComponent(String packageName, String name) {
Intent launch_intent = new Intent("android.intent.action.MAIN");
launch_intent.addCategory("android.intent.category.LAUNCHER");
launch_intent.setComponent(new ComponentName(packageName, name));
launch_intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
this.startActivity(launch_intent);
}
