从服务应用崩溃请求权限

Question

我正在尝试请求

if (ActivityCompat.checkSelfPermission(mContext, Manifest.permission_group.LOCATION) != PackageManager.PERMISSION_GRANTED) {
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
        ActivityCompat.requestPermissions((Activity) mContext, new String[]{Manifest.permission_group.LOCATION}, REQUEST_CODE_ASK_PERMISSIONS);
    }
}
locationManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 0, 0,this);

我收到此错误

请帮忙

Answer 1

mContext 不是 Activity。 所以你不能把它作为一个。 在这种情况下，它是一个应用程序。
