idea_1:use ota replace bootanimation.zip

idea_2:创建一个新的分区,(用于存放bootanimation.zip)可以让上层读写.

idea_3:su cp

前提条件：userdebug版本, 默认关闭selLinux,可root

//df 查看设备分区情况,有些分区系统是不让去写的
adb shell

找到一个可以被命令操作的分区,然后复制动画.

IntentFilter intentFilter = new IntentFilter();intentFilter.addAction(Intent.ACTION_MEDIA_MOUNTED);intentFilter.addDataScheme("file");registerReceiver(AnimationReceiver,intentFilter);BroadcastReceiver AnimationReceiver = new BroadcastReceiver() {@Overridepublic void onReceive(Context context, Intent intent) {if (intent.getAction().equals(Intent.ACTION_MEDIA_MOUNTED)) {String path = intent.getData().getPath() + "/bootanimation.zip";File file = new File(path);if (file.exists()) {long file_size = file.length();long file_mb = file_size / 1048576;Log.d("tag", "file_mb size of = " + file_mb + "MB");if (file_mb <= 30) {execRootCmd(path);}}}}};private int execRootCmd(String path) {int result = -1;DataOutputStream dos = null;try {java.lang.Process process = Runtime.getRuntime().exec("/system/xbin/su");dos = new DataOutputStream(process.getOutputStream());dos.writeBytes("mount -o rw,remount /dev/block/dm-8 /odm" + "\n");//利用命令挂载File seat_file = new File("/odm/boot/seat.zip");if (seat_file.exists()) {dos.writeBytes("rm -rf /odm/boot/seat.zip" + "\n");dos.flush();}File mfile = new File("/odm/boot/");if (!mfile.exists()) {dos.writeBytes("mkdir /odm/boot/" + "\n");dos.flush();}dos.writeBytes("cp " + path + " /odm/boot/" + "\n");dos.flush();dos.writeBytes("chmod 644 odm/boot/bootanimation.zip" + "\n");dos.flush();SystemClock.sleep(500);dos.writeBytes("reboot\n");dos.flush();dos.writeBytes("exit\n");dos.flush();process.waitFor();result = process.exitValue();} catch (Exception e) {e.printStackTrace();} finally {if (dos != null) {try {dos.close();} catch (IOException e) {e.printStackTrace();}}}return result;}

补充:
Android Q(10)开始引进动态分区,分区的大小不好确定.可以去配置文件固定分区大小(不让其动态),或者弄一个文件占位.

bug:Android T bootanimation 时间过长(>50s),会触发bug,现象为System UI ANR.
