android 12 U盘 /mnt/media

• 移动开发

现象

storage下可读取，但/mnt/media_rw不可读取

 /mnt/media_rw/A009-1B4F/rk3568_s-ota-20230704.zip (Permission Denied）

解决方法

把/mnt/media_rw/ 替换为 /storage 

android 12 U盘 /mnt/media

android 12 U盘 /mnt/media

1.在解析ota升级包时，将 /mnt/media_rw/ 替换为 /storage 

if (Build.VERSION.SDK_INT >= 30) {
            if (mImageFilePath.startsWith("/data/media")) {
                tempPath = mImageFilePath.replace("/data/media", "/storage/emulated");
            } else if (mImageFilePath.startsWith("/mnt/media_rw")) {
                tempPath = mImageFilePath.replace("/mnt/media_rw", "/storage");
            }

        }

 2.真正执行升级逻辑时，将 /storage 再替换回  /mnt/media_rw/

        if (Build.VERSION.SDK_INT >= 30) { // Build.VERSION_CODES.R
            Log.d(TAG, "installPackage SDK version >= Build.VERSION_CODES.R,should convert update file path.");
            if (parsedUpdate.mUrl.startsWith("file:///storage/emulated/0")) {
                convertPath = parsedUpdate.mUrl.replace("/storage/emulated/0", "/data/media/0");
                Log.d(TAG, "startsWith(\"file:///storage/emulated/0\")");
            } else if (parsedUpdate.mUrl.startsWith("file:///storage")) {
                convertPath = parsedUpdate.mUrl.replace("/storage", "/mnt/media_rw");
                Log.d(TAG, "startsWith(\"file://storage\")");
            }
            Log.d(TAG, "installPackage update " + parsedUpdate.mUrl + " to " + convertPath);
        }
