android-6.0-marshmallow

问题 I have a problem regarding the camera in the most recent Marshmallow build, more specifically the flashlight. On any pre-Marshmallow version all I need to do to turn the flash on/off was the following: private void turnFlashOn(final Camera camera, int flashLightDurationMs) { if (!isFlashOn()) { final List<String> supportedFlashModes = camera.getParameters().getSupportedFlashModes(); if (supportedFlashModes != null && supportedFlashModes.contains(Camera.Parameters.FLASH_MODE_TORCH)) { mParams

问题 I have an app that observes a public directory on external storage with FileObserver . It works fine on Lollipop devices. I want to add support for Marshmallow , so I set up a Nexus 9 tablet with it. On the Marshmallow device, it fails, on Lollipop device it's OK. On Marshmallow device, the FileObserver does not react to file system events that are caused by other processes. E.g. taking a screenshot, creating files via adb shell. It works fine if the files are created by my app. On

问题 I'm porting an old big application in Cordova 3.4, from Eclipse to Android Studio because this application used a library that now has been updated in Android 6. After some issues with build.gradle and settings.gradle, the App builds, runs and I can make the apk. Every thing works fine on devices with Android 5. With Android 6 on Nexus 9 the app crashes, with a white screen with this error: E/libEGL: validate_display:255 error 3008 (EGL_BAD_DISPLAY) On Internet I've found few answers to this

问题 I'm developing an application that going to be pr-installed (as a system app) on the firmware. from the documentation so far about the relation between system apps, new permissions model, and the protection levels - I don't understand exactly when system app needs (if at all) to request user permission. My problems starts when I try to use the WRITE_EXTERNAL_STORAGE permission. from the documentation I can see that it marked as "dangerous" permission. - does "dangerous" permissions grant

问题 I've just updated my Nexus 5 and my app's feature has stopped working. The reason is that the interface LeScanCallback is not calling the function onLeScan . On the below code, I'm using some deprecated code, but I need to do it since I'm testing some technology. This is how I start my bluetooth adapter: @Override protected void onStart() { super.onStart(); // Check if the device has BLE if (!this.getPackageManager().hasSystemFeature(PackageManager.FEATURE_BLUETOOTH_LE)) { bleNotSupported();

问题 Hi i am updating my application jaffna Temples . so that it can support Android M devices (v 6.0 and above).

问题 I follow this guide to ask for permissions for Android 6.0, https://developer.android.com/preview/features/runtime-permissions.html#support-lib However, I have to destroy my application and re-launch to actually have the WRITE_EXTERNAL_STORAGE permission, otherwise it keeps failing for file creation. Am I missing something? if(ActivityCompat.checkSelfPermission(mContext, Manifest.permission.WRITE_EXTERNAL_STORAGE) == PackageManager.PERMISSION_DENIED){ ActivityCompat.requestPermissions(
