Question

应用程序随机崩溃，显示权限拒绝异常。这是错误日志

Answer 1

我认为你在Marshmallow设备上运行尝试处理权限运行时。

需要读取外部存储

public boolean checkPermissionREAD_EXTERNAL_STORAGE(
        final Context context) {
    int currentAPIVersion = Build.VERSION.SDK_INT;
    if (currentAPIVersion >= android.os.Build.VERSION_CODES.M) {
        if (ContextCompat.checkSelfPermission(context,
                Manifest.permission.READ_EXTERNAL_STORAGE) != PackageManager.PERMISSION_GRANTED) {
            if (ActivityCompat.shouldShowRequestPermissionRationale(
                    (Activity) context,
                    Manifest.permission.READ_EXTERNAL_STORAGE)) {
                showDialog("External storage", context,
                        Manifest.permission.READ_EXTERNAL_STORAGE);

            } else {
                ActivityCompat
                        .requestPermissions(
                                (Activity) context,
                                new String[] { Manifest.permission.READ_EXTERNAL_STORAGE },
                                MY_PERMISSIONS_REQUEST_READ_EXTERNAL_STORAGE);
            }
            return false;
        } else {
            return true;
        }

    } else {
        return true;
    }
}`enter code here`

在Manifest中添加：

<user-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />

如果不起作用
