无法以编程方式从外部存储中删除文件
问题内容:
我正在尝试删除路径下的文件
/storage/714D-160A/Xender/image/Screenshot_commando.png
到目前为止,我所做的是:
try{
String d_path = "/storage/714D-160A/Xender/image/Screenshot_commando.png";
File file = new File(d_path);
file.delete();
}catch(Exception e){
e.printStackTrace();
}
并且文件仍在其位置(未删除:()
另外,我已在清单文件中授予了权限。
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.WRITE_INTERNAL_STORAGE" />
<uses-permission android:name="android.permission.STORAGE" />
问题答案:
public static boolean delete(final Context context, final File file) {
final String where = MediaStore.MediaColumns.DATA + "=?";
final String[] selectionArgs = new String[] {
file.getAbsolutePath()
};
final ContentResolver contentResolver = context.getContentResolver();
final Uri filesUri = MediaStore.Files.getContentUri("external");
contentResolver.delete(filesUri, where, selectionArgs);
if (file.exists()) {
contentResolver.delete(filesUri, where, selectionArgs);
}
return !file.exists();
}
