Android 6 权限访问互联网

Question

一个月前，我编写了我的第一个应用程序，并获得了在 SD 卡上写入的权限，当 activity 开始时，我请求权限：

if (permission != PackageManager.PERMISSION_GRANTED) {

    if (ActivityCompat.shouldShowRequestPermissionRationale(this,
                Manifest.permission.WRITE_EXTERNAL_STORAGE)) {
        AlertDialog.Builder builder = new AlertDialog.Builder(this);
        builder.setMessage("L'app richiede i permessi di scrittura")
                .setTitle("Richiesta Permessi");

        builder.setPositiveButton("OK", new DialogInterface.OnClickListener() {

            public void onClick(DialogInterface dialog, int id) {

                makeRequest();
            }
        });

        AlertDialog dialog = builder.create();
        dialog.show();

    } else {
        makeRequest();
    }
}

这是makeRequest()

private static final int REQUEST_WRITE_STORAGE = 112;
private static String TAG = "PermissionDemo";

protected void makeRequest() {
    ActivityCompat.requestPermissions(this,
            new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE},
            REQUEST_WRITE_STORAGE);
}

@Override
public void onRequestPermissionsResult(int requestCode, String permissions[], int[] grantResults) {
    switch (requestCode) {
        case REQUEST_WRITE_STORAGE: {
            if (grantResults.length == 0
                    || grantResults[0] !=
                    PackageManager.PERMISSION_GRANTED) {

               //Log.i(TAG, "Permission has been denied by user");

                finish();
            } else {
                //Log.i(TAG, "Permission has been granted by user");
                creaConfigurazioneIniziale();
            }
            return;
        }
    }
}

现在我的应用程序需要互联网许可，我已将其放在清单中：

<uses-permission android:name="android.permission.INTERNET" />

还有这个

但是不起作用，我可以做些什么来添加 Internet 和网络的权限？我尝试添加 makereqeust 这个：

protected void makeRequest() {
    ActivityCompat.requestPermissions(this,
            new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE},
            REQUEST_WRITE_STORAGE);
    ActivityCompat.requestPermissions(this,
            new String[]{Manifest.permission.INTERNET},
            REQUEST_WRITE_STORAGE);
    ActivityCompat.requestPermissions(this,
            new String[]{Manifest.permission.ACCESS_NETWORK_STATE},
            REQUEST_WRITE_STORAGE);
}

但不起作用。我该如何解决问题？

Answer 1

请检查link1, link2

对于将访问 Internet 的应用程序，它仍然是强制性的。如果开发人员在未在 Android 清单中定义应用程序的情况下发布应用程序，则在第一次尝试连接时会抛出异常，并且应用程序可能会崩溃。这和以前没什么不同。

安装时授予的有限权限：当用户安装或更新应用时，系统会授予应用请求的属于 PROTECTION_NORMAL 的所有权限。例如，闹钟和互联网权限属于 PROTECTION_NORMAL，因此它们会在安装时自动授予。

谢谢

Answer 2

您不需要请求互联网或 access_network_state 许可，因为 Android 默认授予它。

我们必须检查一些危险的权限

如何检查危险权限？

我按照以前的方式发布代码。假设我们要检查 CAMARA 权限。

public class Utility {

    public static final int MY_PERMISSIONS_REQUEST_CAMERA = 130;

    public static boolean checkPermissionCAMERA(final Context context) {
        int currentAPIVersion = Build.VERSION.SDK_INT;
        if (currentAPIVersion >= android.os.Build.VERSION_CODES.M) {
            if (ContextCompat.checkSelfPermission(context,
                    Manifest.permission.CAMERA) != PackageManager.PERMISSION_GRANTED) {
                if (ActivityCompat.shouldShowRequestPermissionRationale((Activity) context,
                        Manifest.permission.CAMERA)) {
                    AlertDialog.Builder alertBuilder = new AlertDialog.Builder(context);
                    alertBuilder.setCancelable(true);
                    alertBuilder.setTitle("Permission necessary");
                    alertBuilder.setMessage("Camera permission is necessary");
                    alertBuilder.setPositiveButton(android.R.string.yes, new DialogInterface.OnClickListener() {
                        public void onClick(DialogInterface dialog, int which) {
                            ActivityCompat.requestPermissions((Activity) context,
                                    new String[] { Manifest.permission.CAMERA }, MY_PERMISSIONS_REQUEST_CAMERA);
                        }
                    });
                    AlertDialog alert = alertBuilder.create();
                    alert.show();

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

    public static void showDialogOK(final Activity context, String message) {
        AlertDialog.Builder alertBuilder = new AlertDialog.Builder(context);
        alertBuilder.setCancelable(true);
        alertBuilder.setTitle("Permission necessary");
        alertBuilder.setMessage(message);
        alertBuilder.setPositiveButton(android.R.string.yes, new DialogInterface.OnClickListener() {
            public void onClick(DialogInterface dialog, int which) {
                Utility.checkAndRequestPermissions(context);
            }
        });
        AlertDialog alert = alertBuilder.create();
        alert.show();
    }
}

现在在你的 Activity.

里面

if(Utility.checkPermissionCAMERA(this)){
    // Do work
}

并最终覆盖 onRequestPermissionsResult

@Override
public void onRequestPermissionsResult(int requestCode,
        String[] permissions, int[] grantResults) {
    switch (requestCode) {
    case Utility.MY_PERMISSIONS_REQUEST_CAMERA:
        if (ContextCompat.checkSelfPermission(Splash_Activity.this,
                Manifest.permission.CAMERA) == PackageManager.PERMISSION_GRANTED) {
            // do work
        }else{
            // take action
        } 
        break;
    }
}

如何检查多个权限？

                    .toArray(new String[listPermissionsNeeded.size()]),
                    REQUEST_ID_MULTIPLE_PERMISSIONS);
            return false;
        }
        return true;
    }

    public static void showDialogOK(final Activity context, String message) {
        AlertDialog.Builder alertBuilder = new AlertDialog.Builder(context);
        alertBuilder.setCancelable(true);
