Android is a mobile operating system developed by Google, based on the Linux kernel and designed primarily for touchscreen mobile devices such as smartphones and tablets. Android's user interface is based on direct manipulation, using touch gestures that loosely correspond to real-world actions, such as swiping, tapping and pinching, to manipulate on-screen objects, along with a virtual keyboard for text input. In addition to touchscreen devices, variants of Android are also used on notebooks, game consoles, digital cameras, televisions, automobiles and other electronics. Applications are usually developed in Java programming language using the Android software development kit (SDK), but other development environments are also available, including Delphi, Ruby and Visual Studio (using C++).

Referring to above unfinished EE thread,

Q1:
will anything break if I move Whatsapp photos/images from Phone to microSD & if needed,
later move the photos/images back to the phone?

Q2:
Would like to clarify what Tim Green mentioned below: I could not locate it.

"Just because it doesn't cache the email, it still save info about the mailbox that will be needed for connectivity.
The move process may be a bit different depending on the android device but you can do it like this for the most part:

1.Navigate to settings on your phone
2.Tap Apps.
3.Select an app you want to move to the microSD card.
4.Tap Storage.
5.Tap Change if it's there. If you don't see the Change option, the app cannot be moved.
6.Tap Move. "

After installing MobilePass (a 2FA/OTP app for use with Checkpoint
VPN), it has required my Android phone to enter a PIN : previously
I just need to swipe the screen.

The issue is: since MobilePass app is installed, all my various
Whatsapp groups don't give a sound/alert even if I set custom
notifications.  However, the new whatsapp messages will still
pop up (if I set a custom notification).

I would like the sound notifications for new messages at set
by custom notifications.

I had to add a PIN to allow me to look at admin apps, and now I can't go back to swipe or none.  They are grayed out, and they say: Disabled by administrator, encryption policy or credential storage.

I've cleared the device administrators and cleared credentials. I can't decrypt the phone, it just says phone encrpyted and if I press that nothing happens. Using Android 6 on Alcatel Pixi. I've also tried clear the device administrators and clear credentials, RESTART, clear credentials.

Is there a way I can get those swipe or none options back?  Thanks.

#1 After running the "setContentView(gameView);" inside the onCreate method of GameActivity.java, does its onResume() method will be run to start the in order to call the resume() method inside TDView.java ?

#2 Inside resume() method in TDView, does it create a thread of itself and run the code under "run" method ?

gameThread = new Thread(this);
gameThread.start();

#3 What the purpose of "join" under pause method of TDView ? Does it remove the current thread after all the codes under method "run" have been executed ?

Become a CompTIA Certified Healthcare IT Tech

This course will help prep you to earn the CompTIA Healthcare IT Technician certification showing that you have the knowledge and skills needed to succeed in installing, managing, and troubleshooting IT systems in medical and clinical settings.

My question is meant to save much time and energy by asking for a proven advice and pro tips from the experience of an expert who has built with Android/Kotlin/Gradle offline. That is the type of information which helps me very much, and I appreciate it to the utmost.

I have a need to build locally, in full & certainty, sometimes. It should be possible, quite surely in the cases when I have no need to add & resolve new dependencies. Please correct me if I got that wrong: if the JDK, the Studio IDE compiler and Kotlin are installed locally by default, then what I need to be sure about is if Gradle has cached locally the Android libraries I'm using and can resolve all the dependencies without network resources.

If Gradle cannot build a new source without network resources, so can it do it regularly offline after the the first build was done successfully online? i.e. Does Gradle can cache and caches locally everything it needs for a source (that won't add new dependencies)?

And in a case of a code error: do Studio and Gradle cover a reasonable amount of their build error-info offline as well? Or that you'll need to anyway go online and build again to get it?

Below is the Android site's information about the offline mode feature (naturally, it doesn't cover my question):

"Enable offline mode
If you are on a slow network connection, your build times may suffer when Gradle attempts to use network resources to resolve dependencies. You can tell Gradle to avoid using …

I am making an android camera application. My doubt is how do I pass the supported resolutions as parameters to the camera.

So, First I'am getting all the supported resolution sizes:

Size[] sizes = configurationMap.getOutputSizes(ImageFormat.YUV_420_888);
            Log.d("test","size:"+sizes.length);

            for(Size size : sizes){
                Log.d("test","width: "+size.getWidth()+" height"+size.getHeight());
            }
Then I am configuring the input with one of these sizes.

InputConfiguration inputConfiguration = new InputConfiguration(1920,1080,ImageFormat.YUV_420_888);
The I'am passing this input to a capture session

   cameraDevice.createReprocessableCaptureSession(inputConfiguration, Arrays.asList(previewSurface), new CameraCaptureSession.StateCallback() {
                @Override
                public void onConfigured(@NonNull CameraCaptureSession cameraCaptureSession) {
                    try {
                        cameraCaptureSession.setRepeatingRequest(mCaptureRequestBuilder.build(),null,handler);
                    } catch (CameraAccessException e) {
                        e.printStackTrace();
                    }
                }

                @Override
                public void onConfigureFailed(@NonNull CameraCaptureSession cameraCaptureSession) {
                    Toast.makeText(getApplicationContext(),"Camera Preview Failed!!",Toast.LENGTH_SHORT).show();
                }
            },null);

I am developing an android camera application, and I wanted to pass in the capture size to configure the camera before taking a picture.

This is my code:

        try {
            mCaptureRequestBuilder = cameraDevice.createCaptureRequest(CameraDevice.TEMPLATE_PREVIEW);
            mCaptureRequestBuilder.addTarget(previewSurface);

            InputConfiguration inputConfiguration = new InputConfiguration(1920,1080,ImageFormat.JPEG); //error here.

            cameraDevice.createReprocessableCaptureSession(inputConfiguration, Arrays.asList(previewSurface), new CameraCaptureSession.StateCallback() {
                @Override
                public void onConfigured(@NonNull CameraCaptureSession cameraCaptureSession) {
                    try {
                        cameraCaptureSession.setRepeatingRequest(mCaptureRequestBuilder.build(),null,handler);
                    } catch (CameraAccessException e) {
                        e.printStackTrace();
                    }
                }

                @Override
                public void onConfigureFailed(@NonNull CameraCaptureSession cameraCaptureSession) {
                    Toast.makeText(getApplicationContext(),"Camera Preview Failed!!",Toast.LENGTH_SHORT).show();
                }
            },null);
}
So, I am trying to pass an input configuration to the camera here. My problem is I'am getting an error in the InputConfiguration line. This is my error:

I wish to update my Android SDK/NDK  tools on Embarcadero RAD Studio 10.2 from SDK API 34 (Android version7) to SDK API 28 (Android version 9).
several videos on U-tube show how to install Android tools into the IDE using Gettit but in my list of Gettit packages, Android development tools is missing ?

Is there a way to update the SDK/NDK using RAD Studio ( C++ builder) ?

I'm getting software conflict errors such as Gradle could not find the path to the JDK.
After much research and trial & error experiments I've gained more knowledge but still didn't get a straight solution to how that setup should be done correctly.

I've tried several software/settings combinations, hacks and answers I found on Stack Exchange and such sites. But then other issues pop up (and a Gradle scan shows more of them) and what is needed is the correct explanation of how that should be done to build a robust environment the way it was meant to be by the developers.

Android Developer site, the official site from which to download Android Studio, doen't state there's a need for additional JDK/JRE installation, and I also found within Studio a differed version than the latest and no JDK (which is the one that, as I understand, Studio actually needs).
C:\Program Files\Android\Android Studio\jre

I'm using the latest versions on a Windows 8.1 on a Lenovo Y50-70 (64 bit, 16GB RAM):
Android Studio 3.1.2
Gradle 4.4 through Gradle plugin 3.1.2
JDK 10.0.2 (Oracle states it includes the JRE).

I've already installed and uninstalled a couple of times and wouldn't like to further mess up anything (OS registry etc.), what's needed is an experienced expert on-point advise.

Thanks in advance.

In an Xamarin Forms project under Visual Studio 2017, I can't get the FCM (Firebase Cloud Messaging) token for Android devices (.Droid project) to register it to FCM.

I created an application on the Firebase console, and retrieved the ApplicationId, ApiKey, ProjectId and GcmSenderId.

Here is the code I use in the .Droid project on Xamarin.Forms:

var options = new FirebaseOptions.Builder()
                    .SetApplicationId("xxxx")
                    .SetApiKey("xxxxxxxxxxxxx") 
                    .SetProjectId("xxxxxxxxx")
                    .SetDatabaseUrl("xxxxxxxxxxxxxxx")
                    .SetGcmSenderId("xxxxxxxxxxxx")
                    .Build();

FirebaseApp app = FirebaseApp.InitializeApp(Android.App.Application.Context, options);
String token = FirebaseInstanceId.Instance.Token; // RETURNS NULL
String authorizedEntity = "xxxxxxxxxx";
String scope = "GCM";
String token2 = FirebaseInstanceId.Instance.GetToken(authorizedEntity, scope); // ALSO RETURNS NULL

Open in new window


I do not understand why the GetToken () function returns NULL.
Can you help me please ?

For the UWP project, I can recover it by the following method:
var channel = await PushNotificationChannelManager.CreatePushNotificationChannelForApplicationAsync ();
String Token = channel.Uri;

I followed this doc:
