Start Activity Intent from Android Application - android-activity

Question

I have an activity that holds a handler that I need to be running for the whole app. What I need to do is call the handler activity whenever main activity starts up, then upon executing a function at handler activity, handler activity should start the intent into second activity.
This is my code:
public class MyApp extends Application {
public void onCreate() {
h = new Handler() {
#Override
public void handleMessage(Message msg) {
Bundle b = msg.getData();
Log.d("tag",b.getString("msg"));
//THIS IS WHERE I WANT TO OPEN SECONDACTIVITY
}
};
}
}
MyApp is a global Application class I use to run a socket connection across the whole app. It needs to be alive as long as the app is running.

Answer 1

Its simple
Intent intent = new Intent(YourActivityClass.this, SECONDACTIVITY.class);
startActivity(intent);

Answer 2

public class MyApp extends Application {
public void onCreate() {
h = new Handler() {
#Override
public void handleMessage(Message msg) {
Bundle b = msg.getData();
Log.d("tag",b.getString("msg"));
Intent myIntent = new Intent(this, YourSecondActivity.class);
startActivity(myIntent);
}
};
}
}
Also add this to your manifest file
<activity android:name=".YourSecondActivity" />

Answer 3

Well, It turns out that I need to add: i.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
Intent i = new Intent(MyApp.this, SecondActivity.class);
i.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(i);
Because From MainActivity, I called MyApp (An class to maintain global application state). Then in MyApp, I process something and then I call SecondActivity.

Answer 4

First You add the activity information in AndroidManifest.xml LIKE
<activity
android:name="com.assignment.matchnumber.PlayActivity"
android:label="#string/app_name" >
<intent-filter>
<action android:name="com.assignment.matchnumber.PLAY" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>
Then put this in your MyApp activity where you want.
Intent openPlayActivity = new Intent("com.assignment.matchnumber.PLAY");
startActivity(openPlayActivity);
