Question

I have an activity that opens txt files. And everytime a user wants to open a txt file, my app will be able to open it. My question is, how do I pass the path of the file to be opened to my activity? And, how do I receive the path programmatically? In short, what are the things I have to do besides setting the intent filter in the manifest file to allow my app to open a txt file upon clicking that file?

Answer 1

You will need to use a Broadcast Receiver, but not sure what intent-filter you have to use.

Maybe something to try is adding something like this to your manifest:

<receiver android:name="MyBroadcastReceiver">
  <intent-filter>
    <action android:name="android.intent.action.ACTION_VIEW" />
    <action android:name="android.intent.action.ACTION_EDIT" />
    <action android:name="android.intent.action.ACTION_PICK" />
  </intent-filter>
</receiver>

Then you need to create your MyBroadcastReceiver class like this:

public final class MyBroadcastReceiver extends BroadcastReceiver
{
  @Override
  public void onReceive(Context context, Intent intent)
  {
    // Your receiver code here...
  }
}

And then check into the onReceive method the data received into the Intent when you try to open a file. That way you may know what data will arrive into the Intent.

Hope it helps.
