问题 I keep hoping some code will appear on the internet, but getting nowhere ;) I am running this github example. WebRTC incoming I420Frame object seems to have 3 arrays of yuvPlanes A typical Android camera app gets PreviewCallback.onPreviewFrame byte[] as a single array of bytes. My job is to stream an image as I420 at regular interval of time. Can someone help me in how to generate a I420Frames yuvPlanes from single byte[] array like JPEG/PNG file? It is pretty critical.

问题 Originally I was adding information (Strings) and a photo (from drawable) to card views. I had it working from a list and adding it to the cards within a recycler view using an adapter and such. Now I'm trying to migrate to saving this information using the Room Persistence Library and instead of adding dummy info in the code I am going to make it come from user input, as I'm trying to implement this I have discovered that saving images to Room DB is not too easy. The strings are working fine

问题 This has bothered me for a little while now. I may be over reacting, let me know if I am. But, I feel like adding image assets to your Android Studio project is harder than it should be. Not necessarily saying it's difficult to do, but I feel like it should be one of the easiest things to do. I am a bit new to AS, so I could be way out of line here. I'm working on a project, and I want to add a test image real quick to put in an image view. Not having done this yet I just assume I can click

问题 In my app I want to display different icons for the application. Changes should be according to the scenario. For example, it will mark the number of days remaining for the task completion.

问题 Is it documented (or reasonable to assume) that BitmapFactory.decodeByteArray(...) can be expected to recognize any of the image formats listed here? 回答1: Yes, it's reasonable to assume (a bit more so if you take a peek at the source code of AOSP). The JNI native methods for BitmapFactory are in BitmapFactory.cpp . https://github.com/android/platform_frameworks_base/blob/master/core/jni/android/graphics/BitmapFactory.cpp Since both BitmapFactory.decodeByteArray() and the BitmapDrawable

问题 I have an imagebutton that I would like to make shake/wiggle when it is touched. I would like it to wiggle in a manner similar to iPhone app icons do when they are pressed for a very long time. Thanks! 回答1: try to use this one: <set xmlns:android="http://schemas.android.com/apk/res/android"> <rotate android:duration="70" android:fromDegrees="-5" android:pivotX="50%" android:pivotY="50%" android:repeatCount="5" android:repeatMode="reverse" android:interpolator="@android:anim/linear

问题 Is there any drawback in only using xxhdpi images and letting android scale the images? (Yes it might be more cpu intensive, but is it notable?) I tested it on a samsung s2 and the difference were small. Is there a restriction to only use this if set minSdk to XX, becaus there were no xxhdpi? 回答1: Here are a couple drawbacks I can think of: More CPU intensive to resize the images, the app will use more battery and might feel more sluggish, especially on older devices. The images that you are
