I am not sure why my code isn't working, following the android developer guide this should work. I assume that it is because I don't have a preferences file created, I am not sure how to go about that.
Im pretty much a newbie at this so i could use some help to know why does my app keep crashing ?
I have created a FragmentActivity of 2 tabs.
I am using the Twitter4J Library and I am trying to implement some Async Tasks to make some calls to the service as follows.
public class TweetsActivity extends Activity {
/** Called when the activity is first created.
I have two activities:
public class MainActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
public void click(View view) {
Intent intent= new Intent(this, TranslucentActivity.class);
startActivity(intent);
}
}
public class TranslucentActivity extends Activity
I want to lock the screen of the app on button click
I have written the code as
public class MainActivity extends DeviceAdminReceiver{
public void makeTest()
{
System.out.println("Entered Main Class");
}
public class Controller extends Activity {
static final int RESULT_ENABLE = 1;
Button powerOff;
int amountOfTime =20*1000;
Context context = this;
DevicePolicyManager mDPM;
ActivityManag
I have a string "sss" and a character array {'s','s','s'}. I converted the array to string but the message "both are equal" is not printed upon comparing them. Why?
I have this code where i want to display new fragments for each tab .
public class Second extends FragmentActivity{
private TabHost mTabHost;
private static final String TAG_1 = "tab1";
private static final String TAG_2 = "tab2";
private static final String TAG_3 = "tab3";
private static final String TAG_4 = "tab4";
Fragment srkt_fragment,srk2_fragment,holl_fragment,bink_fragment;
EditText
@Override
public void onSaveInstanceState(Bundle savedInstanceState) {
// Save UI state changes to the savedInstanceState.
// This bundle will be passed to onCreate if the process is
// killed and restarted.
savedInstanceState.putLong("lastSend", lastSent);
//more variables stored
}
/** Called when the activity is first created.
