OnActivityResult not called for startActivityForResult

I have MainActivity with an options menu with the 'settings' element.

When I launch SettingsActivity , everything works fine until we click on save and try completing SettingsActivity . This activity ends, but appears to close the parental activity. I am working on this in Eclipse. Eclipse says something is still working because it allows me to press the stop button. I have a timer thread running in MainActivity , but I tested this without this thread and it still doesn't return to onActivityResult() .

I run SettingsActivity this way:

 public static final int ACTIVITY_CREATE = 1; @Override public boolean onOptionsItemSelected(MenuItem item) { switch (item.getItemId()) { case R.id.settings: try { Intent intent = new Intent(this, SettingsActivity.class); startActivityForResult(intent, ACTIVITY_CREATE); } catch (Exception e) { Log.e(TAG, e.getMessage()); finish(); } return true; default: return super.onOptionsItemSelected(item); } }

I expect that finish () in SettingsActivity will return me to this function, but it is not. I have a breakpoint set here and it never gets here:

  @Override protected void onActivityResult(int requestCode, int resultCode, Intent intent) { super.onActivityResult(requestCode, resultCode, intent); switch (requestCode) { case (ACTIVITY_CREATE): { if (resultCode == RESULT_OK) { } break; } } }

Here is a simple SettingsActivity parameter:

  public class SettingsActivity extends Activity implements View.OnClickListener { private Button save; @Override public void onCreate(Bundle b) { super.onCreate(b); setContentView(R.layout.settings); save = (Button) findViewById(R.id.save); save.setOnClickListener(this); return; } @Override public void onClick(View v) { switch (v.getId()) { case R.id.save: Intent intent = new Intent(); intent.putExtra("ip", ipText.getText().toString()); setResult(RESULT_OK, intent); finish(); break; default: break; } return; } } // public class SettingsActivity extends Activity {

In startup mode, the main activity is set to "standard".

My question is: why am I not returning to onActivityResult () in the calling activity?

Thanks Bob

Here is the manifest file:

  <?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.MyStuff" android:versionCode="1" android:versionName="1.0"> <application android:icon="@drawable/icon" android:label="@string/app_name"> <activity android:name=".CTNet" android:label="@string/app_name" android:screenOrientation = "fullSensor" android:configChanges = "orientation|screenSize|keyboardHidden" android:launchMode="singleTask" > <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity> <activity android:name=".SettingsActivity" > </activity> </application> <uses-sdk android:minSdkVersion="8" /> <!-- after targetSdkVersion --> <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /> <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" /> <uses-permission android:name="android.permission.INTERNET" /> <uses-feature android:glEsVersion="0x00020000" android:required="true" /> </manifest>

Trying to add a detailed logarithm here:

I believe because launchMode , view it in AndroidManifest

Try it with singleTop

http://developer.android.com/guide/topics/manifest/activity-element.html#lmode

[Changed]

Do this and tell us what happens when you click in the settings window.

 @Override public boolean onOptionsItemSelected(MenuItem item) { switch (item.getItemId()) { case R.id.settings: Intent intent = new Intent(this, SettingsActivity.class); startActivityForResult(intent, ACTIVITY_CREATE); break; } return super.onOptionsItemSelected(item); }

Try setting mainActivity as

  android:launchMode="singleTask"

in your AndroidManifest.

Try changing the method from protected to public

I found a problem. I had a finish () at the end of the MainActivity onStop () function.
