Permission Denial: not allowed to send broadcast android.intent.action.MEDIA_MOUNTED
当在Android4.4上进行图片的扫描功能开发时一般会使用:sendBroadcast(new Intent(Intent.ACTION_MEDIA_MOUNTED, Uri.parse("file://"+ Environment.getExternalStorageDirectory()+ picPath)));的广播
因为Android4.4中限制了系统应用才有权限使用广播通知系统扫描SD卡,所以会抛题目异常。
解决方法:使用MediaScannerConnection执行具体文件或文件夹进行扫描,核心代码如下:
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) { // 判断SDK版本是不是4.4或者高于4.4 String[] paths = new String[]{Environment.getExternalStorageDirectory().toString()}; MediaScannerConnection.scanFile(mContext, paths, null, null); } else { final Intent intent; if (f.isDirectory()) { intent = new Intent(Intent.ACTION_MEDIA_MOUNTED); intent.setClassName("com.android.providers.media", "com.android.providers.media.MediaScannerReceiver"); intent.setData(Uri.fromFile(Environment.getExternalStorageDirectory())); Log.v(LOG_TAG, "directory changed, send broadcast:" + intent.toString()); } else { intent = new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE); intent.setData(Uri.fromFile(new File(path))); Log.v(LOG_TAG, "file changed, send broadcast:" + intent.toString()); } mContext.sendBroadcast(intent); }
