问题 Galaxy s4 Screen: 4.99", 1920x1080 (FullHD). Which the res folder would be used in FHD and what's the dpi value should be set? xhdpi or xxhdpi? And how can I calculate it? I didn't find any info in the developer docs and in the screens_support article 回答1: It's 441 dpi, isn't it? So almost certainly xxhdpi, which is already supported in the Android framework. But why worry about it at this time? Assuming you're already supporting xhdpi, the likelihood that the average user can detect the

问题 I'm writing a camera app and am having an issue with the S3. Whenever I start recording, the display goes to garbage (see screenshots below). Then, when I stop recording I get an exception: 10-02 13:36:31.647: E/MediaRecorder(24283): stop failed: -1007 10-02 13:36:31.647: D/AndroidRuntime(24283): Shutting down VM 10-02 13:36:31.647: W/dalvikvm(24283): threadid=1: thread exiting with uncaught exception (group=0x40c49a68) 10-02 13:36:31.647: E/AndroidRuntime(24283): FATAL EXCEPTION: main 10-02

问题 I'm trying to shoot picture and store it into internal storage by using the following code: Intent intent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE); takenPhoto = new File(uploadsFolder, getNewPicFileName()); intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(takenPhoto)); startActivityForResult(intent, SHOOT_MEDIA_REQUEST_CODE); The problem is that on Nexus S and Galaxy S devices default and the single orientation for ACTION_IMAGE_CAPTURE intent is landscape. If i

问题 Seems like Samsung disabled their overscroll (probably due to an Apple suit). I have an implementation of a view that extends ScrollView and overrides protected boolean overScrollBy(int deltaX, int deltaY, int scrollX, int scrollY, int scrollRangeX, int scrollRangeY,int maxOverScrollX, int maxOverScrollY, boolean isTouchEvent) { ... return super.overScrollBy(deltaX, deltaY, scrollX, scrollY, scrollRangeX, scrollRangeY, 0, metrics.widthPixels,isTouchEvent); } On every other device (Gingerbread

问题 I have an app on the Play Store, it has an IntentService that does some work when the app starts, and it's causing native crashes on Android 5.0. This service just scans the assets folder for app updating purposes. Specifically, this crash seems to happen on Samsung S5 after the ugrade to Lollipop, but I don't know if it's strictly related to that device, as it's an Italian app and here that's still the only widely diffuse (i.e. that I know of) device that's getting Lollipop. However, I tried

问题 i need to have the menu button shown for some activities on galaxy nexus . i can't find how to do that, since it hides it by default . i don't wish to create an action bar since it takes more space that i want to use to other things . when setting the "android:targetSdkVersion" value to lower than 14 , it seems to show the menu button , but otherwise, it hides it . btw, the activity needs to be full screen , with no title/action bars . it is very weird that this button is not shown by default

问题 I know this question has been asked before but its been a long time. Asking this question again to gather any new hacks/thoughts/approaches. I need to access both front and back camera simultaneously. So far I have tried implementations using android camera API (Dual Camera- by Jens) and camera2 API. Both implementations work fine on devices having hardware support(Dual Image Signal Processors) for dual camera feature.I have tested and both implementations works fine on HTC one M8(Snapdragon

问题 I'm currently working on a cool Android game which was about to be released real soon. Some of our beta testers started complaining that the game crashes with the “too many open files” error message. I've tried simulating this problem on the AVD emulator but couldn't reproduce the error. Afterwards, I realized that only our Galaxy S3 and Asus Nexus 7 testers were complaining. I found this bug issue on Android's bug tracker and it sounds quite similar to what is happening to me. This sounds

问题 The new Samsung Galaxy S4 have and interesting new type of gestures called " Air Gesture " that use an infrared sensor to process users hand movement in front of the screen, adding a " pre-touch "/" proximity " event, in wich the fingers are detected before the touch. I'd like to use this " Floating Touch " event in one of my apps. I searched both on Google and in the Samsung Developers Center, but I coudnt find any API or information about that. Are the API available or is too early? Does
