Hi,
I believe the title says it all. I tried to find the solution here but without success. While Im satisfied with my Nexus 7 case, I found out that sometimes if I just close it and put the tablet into bag it fails to turn the screen off. So, Id prefer to do that manually.
Is there a software way to disable the magnetic sensor? I dont want to play tailor with my case ...
Just manually turn it off. Closing the case won't turn your screen back on...
If the problem is that as the tab shuffles around in your bag and the case cover opens just enough to turn it back on, that's a different issue. Then you'll need some type of band or something to put around it.

Thanks, that will do. :good: But is there really NO sw way to disable it? I dont like automatic functions just lying around ...

Unless you find a way in the code to disable it or figure out how to physically remove it.
or... just get a case with out a magnet in it.

Ive been hoping in someone else finding the way to disable it in the code. Anyway, I guess Ill get another case and see ... THX! :good:

Until seeing it on youtube, I wasn't even aware of this feature. The amazing thing to me is the fact that the actual case sold for the N7 at the google store does not have this feature (ie. no magnet)......
Im afraid I took the matters into my own hands and solved my magnetic problem once and for all ... :laugh:

Your case isn't nearly as attractive now.
Seriously, I can't see how this was a real issue unless your case was designed badly. Example; some flip-around cases if not shielded will turn the N7 off when flipped around.

Well, small hole inside the case isnt a big deal for me. Anyway, the problem was that the case managed to turn the tablet off only when closed really good. And if closed, only a few milimeters (say 2) of movement of the front cover to the left made the case wake my N7. I couldnt really be sure what would the Thing do in my bag - but the case itself is good, co I kept it this way.
This can be done strictly via software. Here is a modified version of the kernel driver from drivers/input/lid.c that allows you to enable/disable this feature. By default, it acts normally. To disable the magnetic switch, do "echo 0 > /sys/module/lid/parameters/lid_enabled", or use any other app you want to write to that file. To enable it again, just write a non-zero value to the parameter. Ive only tested it on my nexus7, but it seems to work perfectly.

So how would one go about implementing this modified code? Personally, I can't believe that there is not a standard setting to enable/disable this feature, but it ROM developers and/or users can implement this modified code easily, that would be a big help!
Thanks.

The code was for reference. EDIT: No it's not, I'm an idiot.
Not the way I read it. The modified code has to be built into a kernel to access the option file.

Yes, this is one of the files that make up the kernel, with about 10 lines added to it. You would have to replace the file in the kernel source code, build the kernel, insert that kernel into a boot.img, and flash it to your tablet. If you can't manage all that, then you could pester the person who does make the kernel you're using to add it.

im interested in trying this on the sprint GS4.
can you possibly be a little more detailed on what i need to do?
thank you very much.
In my opinion the best solution to this problem is two steps:
1) Remove any magnet in the case cover. Disables smart cover feature physically rather than software.
2) Use NFC tags with programs configured to control exactly the items needed, e.g. sleep mode, settings, wi-fi, etc.
This may require two to four NFC tags, one for each major scenario. These might be "deep sleep, battery save", "sleep with fast restore", "wake no communicate", "wake and communication", etc. You could put the tags on a strip of material along with color codes. Touch the tag to the NFC sensor and no messing around.
As others may notice, I attended the XDA dev conference. LOL
As I know all magnetic cases or stuffs are harmful for mobile phones or tablets...
By the way do you guys think that, can this little magnet in the case ، hurm n7 in the long term ?
Xposed Module
Somebody made a Xposed module for the Moto G that disables the magnetic lock.
It could work on the N7, but i dont have a smart cover to try.

I ordered my N7 during the IO in which it was announced. Been in a magnetic case since then, so about a year and a half. What do you "know" is harmful? A static magnetic field is unlikely to harm solid state electronics or affect their operation.

I'm developing an app with a count down time and I'm looking for a way to tie into the built in alarm sounds, or at least a way to set one programmatically,
Anyone ideas?
I'm using the DispatcherTimer for counting ticks.
Example code below:
Code:
if (remaining.TotalSeconds <= 0)
{
this._dispatcherTimer.Stop();
// Alarm callingmethod goes here
}
dispatcherTimer = new System.Windows.Threading.DispatcherTimer();
dispatcherTimer.Tick += new EventHandler(dispatcherTimer_Tick);
dispatcherTimer.Interval = new TimeSpan(0,0,1);
dispatcherTimer.Start();
// System.Windows.Threading.DispatcherTimer.Tick handler
//
// Updates the current seconds display and calls
// InvalidateRequerySuggested on the CommandManager to force
// the Command to raise the CanExecuteChanged event.
private void dispatcherTimer_Tick(object sender, EventArgs e)
{
dispatcherTimer.Stop();
// Call alarm here
}
No, I need to know how to call the alarm sound. The example I showed was how it was going to be called.
The app is completed, except for this little extra I would like to add.
Code:
var alarm = new Alarm(name);
alarm.Content = content;
alarm.Sound = new Uri("/Ringtones/Ring01.wma", UriKind.Relative);
alarm.BeginTime = beginTime;
alarm.ExpirationTime = expirationTime;
alarm.RecurrenceType = RecurrenceInterval.None;
ScheduledActionService.Add(alarm);

I'll let you know how it works ... thanks.
So I am building a program with a notification that activates 3 hours after the activity is stopped (for testing purposes I am currently using minutes). This is what my main activity looks like...
Code:
Override
public void onStop() {
super.onStop();
Calendar calendar = Calendar.getInstance();
int alarmTime = (calendar.get(Calendar.MINUTE)) + 3;
calendar.set(Calendar.MINUTE,alarmTime);
Intent intent3 = new Intent(getApplicationContext(),timeReceiver.class);
PendingIntent pendingIntent3 = PendingIntent.getBroadcast(getApplicationContext(),100,intent3,PendingIntent.FLAG_UPDATE_CURRENT);
AlarmManager alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE);
alarmManager.setRepeating(AlarmManager.RTC_WAKEUP,calendar.getTimeInMillis(),AlarmManager.INTERVAL_DAY,pendingIntent3);
}
@Override
protected void onRestart() {
super.onRestart();
//this.onCreate(null);
}
This is what my broadcast receiver class looks like...
Code:
public class timeReceiver extends BroadcastReceiver{
@Override
public void onReceive(Context context, Intent intent) {
NotificationManager notificationManager =(NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
Intent repeating_intent = new Intent(context, RepeatingActivity.class);
repeating_intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
PendingIntent pendingIntent = PendingIntent.getActivity(context,100,repeating_intent,PendingIntent.FLAG_UPDATE_CURRENT);
NotificationCompat.Builder builder = new NotificationCompat.Builder(context);
builder.setContentIntent(pendingIntent);
builder.setSmallIcon(android.R.drawable.arrow_up_float);
builder.setContentTitle("Timer Notification");
builder.setContentText("blaaah blaaah blah");
builder.setAutoCancel(true);
notificationManager.notify(100,builder.build());
}
}
3 minutes after running the stop code the timer is activated the way it's supposed to, however my problem is that if the code is executed a second time within this 3 minute period - then no notification is pushed at all. My hope is that the alarm would reset and trigger 3 minutes after the last execution of the onStop() method, but it doesn't. I don't really understand why it doesn't, if anyone could give me insight/ a possible solution I would be grateful. Also the SDK version is 24.
I've already worked on a alarm scheduler (notification) just yesterday.
So here comes my working code (you can find it in github / binogure-studio):
Code:
public void schedule_local_notification(String title, String content, int delay, int notification_id) {
// delay is after how much time(in millis) from current time you want to schedule the notification
NotificationCompat.Builder builder = new NotificationCompat.Builder(context, activity.getPackageName() + CHANNEL_ID)
.setContentTitle(title)
.setContentText(content)
.setAutoCancel(true)
.setSmallIcon(R.drawable.ic_stat_name)
.setLargeIcon(BitmapFactory.decodeResource(context.getResources(), R.mipmap.ic_launcher))
.setSound(RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION));
Intent intent = new Intent(context, Godot.class);
PendingIntent intentActivity = PendingIntent.getActivity(context, notification_id, intent, PendingIntent.FLAG_CANCEL_CURRENT);
builder.setContentIntent(intentActivity);
Notification notification = builder.build();
Intent notificationIntent = new Intent(context, LocalNotificationReceiver.class);
notificationIntent.putExtra(LocalNotificationReceiver.NOTIFICATION_ID, notification_id);
notificationIntent.putExtra(LocalNotificationReceiver.NOTIFICATION, notification);
PendingIntent pendingIntent = PendingIntent.getBroadcast(context, notification_id, notificationIntent, PendingIntent.FLAG_CANCEL_CURRENT);
long futureInMillis = SystemClock.elapsedRealtime() + delay * 1000;
AlarmManager alarmManager = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);
alarmManager.set(AlarmManager.ELAPSED_REALTIME_WAKEUP, futureInMillis, pendingIntent);
}
public void cancel_local_notification(int notification_id) {
try {
Intent intent = new Intent(context, LocalNotificationReceiver.class);
PendingIntent pendingIntent = PendingIntent.getBroadcast(context, notification_id, intent, PendingIntent.FLAG_UPDATE_CURRENT);
AlarmManager alarmManager = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);
alarmManager.cancel(pendingIntent);
} catch (Exception ex) {
Log.w(TAG, "Cannot show local notification: " + ex.getMessage());
}
}
Hi,
First, a disclaimer.
I am a Java and xposed noob. My background is in embedded C development so I can get by with some simple Java code and thanks to the great tutorials online I have been able to put together an xposed module but I'm struggling with a problem that is beyond my abilities now and am reaching out to the community for help.
Next, the background.
I have an Android head unit in my car. There is an app that provides me with CarPlay functionality but none of the controls on the steering wheel work with the app. When I analysed the code I found that they handle all of their button inputs using proprietary methods that do not inject an event into any input streams. I wrote an xposed module to hook the button press methods and then inject a proper input into one of the event streams.
Initially I tried to use the command line 'input' command to do this but since it is a Java app and takes about 1s to load it was too slow. My only other option was to create a virtual device on an input stream that I could then use to inject keypresses through the hooked method. To create a virtual device I needed to write C code that my xposed module would be able to access through the JNI. Long story short, after some pain I was able to get the native library integrated into the project and compiling using the NDK.
Finally, the problem.
When I was using the module without the native library it worked but just with a large delay because of the time it takes to load the 'input' java app. I was able to see logs from the module in the logcat as I hooked the method and as I went through the various actions within the hook.
As soon as I introduce the native library though the entire xposed module just stops running completely. I do not get any logs from the module even though I have installed, activated and rebooted. It shows up in the xposed installer but it just does nothing. The funny thing is that this happens even if I make no reference whatsoever to any native functions within the library. All I need to do to kill the module is to build it with the System.loadlibrary line in the Main.java uncommented. As soon as I comment that piece of code out the module starts to hook the function and output logs again. Below is the code from the Main.Java that I am referring to. I am happy to make any manifest, C and gradle files available too. Looking for any ideas as to why the module dies completely as soon as I include this...

The issue with native library is quite strange and I cannot help with it as my experience with native libs is zero.
But maybe try a different method of injecting media key events.
Create a method:
Code:
void injectKey(int keyCode) {
try {
final long eventTime = SystemClock.uptimeMillis();
final InputManager inputManager = (InputManager)
mContext.getSystemService(Context.INPUT_SERVICE);
int flags = KeyEvent.FLAG_FROM_SYSTEM;
XposedHelpers.callMethod(inputManager, "injectInputEvent",
new KeyEvent(eventTime - 50, eventTime - 50, KeyEvent.ACTION_DOWN,
keyCode, 0, 0, KeyCharacterMap.VIRTUAL_KEYBOARD, 0, flags,
InputDevice.SOURCE_KEYBOARD), 0);
XposedHelpers.callMethod(inputManager, "injectInputEvent",
new KeyEvent(eventTime - 50, eventTime - 25, KeyEvent.ACTION_UP,
keyCode, 0, 0, KeyCharacterMap.VIRTUAL_KEYBOARD, 0, flags,
InputDevice.SOURCE_KEYBOARD), 0);
} catch (Throwable t) {
// something went wrong
XposedBridge.log(t.getMessage());
}
}
Then just do: injectKey(KeyEvent.KEYCODE_MEDIA_PREVIOUS);
And maybe try playing with different KeyEvent flags and attrs.
Thanks so much for this suggestion! Any idea if this injects at a java level or if it depends on there being a keyboard input device available on one of the /dev/input/eventX streams? The android device that I am using has no keyboard available on any of those input streams. Will give it a try nonetheless

Simply use whatever InputDevice that you think should work in your case.
The method basically calls this:
https://android.googlesource.com/pl.../android/hardware/input/InputManager.java#869
which is then propagated to Input Manager Service here:
https://android.googlesource.com/pl...oid/server/input/InputManagerService.java#598
which then calls nativeInjectInputEvent
