撤销权限 android.permission.CALL_PHONE

Revoked permission android.permission.CALL_PHONE

我正在尝试使用以下代码以编程方式呼叫号码:

 String number = ("tel:" + numTxt.getText());
 Intent intent = new Intent(Intent.ACTION_CALL);
 intent.setData(Uri.parse(number));
 startActivity(intent);

我在清单中设置了权限:

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

我正在使用真实设备进行测试和调试,它是带有 Android M 的 Nexus 5,我的 compileSdkVersion 是 23。我收到以下安全异常:

error: Permission Denial: starting Intent { act=android.intent.action.CALL dat=tel:xxxxxxxxxx cmp=com.android.server.telecom/.components.UserCallActivity } from ProcessRecord{cbbd7c1 5228:com.dialerTest.DialerApp/u0a96} (pid=5228, uid=10096) with revoked permission android.permission.CALL_PHONE

我在网络和这个社区中搜索了类似的 Q/A,但找不到答案。任何帮助将不胜感激。

在 android 6.0(Api 23 级)中,我们有一个叫做 "Runtime Permissions" 的东西。你必须阅读它。

您可以找到文档 here

权限CALL_PHONE属于危险权限组。
因此,如果您的应用目标 SDK 为 23 或更高版本,并且您的设备在 Android 6.0 或更高版本上为 运行,则您必须在应用为 运行 时请求 CALL_PHONE 权限。

示例:

String number = ("tel:" + numTxt.getText());
mIntent = new Intent(Intent.ACTION_CALL);
mIntent.setData(Uri.parse(number));
// Here, thisActivity is the current activity
if (ContextCompat.checkSelfPermission(thisActivity,
            Manifest.permission.CALL_PHONE)
    != PackageManager.PERMISSION_GRANTED) {

    ActivityCompat.requestPermissions(thisActivity,
            new String[]{Manifest.permission.CALL_PHONE},
            MY_PERMISSIONS_REQUEST_CALL_PHONE);

    // MY_PERMISSIONS_REQUEST_CALL_PHONE is an
    // app-defined int constant. The callback method gets the
    // result of the request.
} else {
    //You already have permission
     try {
        startActivity(mIntent); 
    } catch(SecurityException e) {
       e.printStackTrace();
   }
}

当您的应用请求权限时,系统会向用户显示一个对话框。当用户响应时,系统会调用您应用的 onRequestPermissionsResult() 方法,将用户响应传递给它。

@Override
public void onRequestPermissionsResult(int requestCode,
    String permissions[], int[] grantResults) {
  switch (requestCode) {
    case MY_PERMISSIONS_REQUEST_CALL_PHONE: {
        // If request is cancelled, the result arrays are empty.
        if (grantResults.length > 0
            && grantResults[0] == PackageManager.PERMISSION_GRANTED) {

            // permission was granted, yay! Do the phone call

        } else {

            // permission denied, boo! Disable the
            // functionality that depends on this permission.
        }
        return;
    }

    // other 'case' lines to check for other
    // permissions this app might request
  }
}

您的代码只有在您发出 ACTION_DIAL 时才能工作,而不是 ACTION_CALL 需要请求许可的地方,因此如果您想拨打电话,请按照以下示例操作:

清单:

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

代码:

import static android.Manifest.permission.CALL_PHONE;

Intent i = new Intent(Intent.ACTION_CALL);
i.setData(Uri.parse("tel:0612312312"));
/*
Intent i = new Intent(Intent.ACTION_DIAL);
i.setData(Uri.parse("tel:0612312312"));
if (i.resolveActivity(getPackageManager()) != null) {
      startActivity(i);
}*/
if (ContextCompat.checkSelfPermission(getApplicationContext(), CALL_PHONE) == PackageManager.PERMISSION_GRANTED) {
      startActivity(i);
} else {
      requestPermissions(new String[]{CALL_PHONE}, 1);
}

片段class

第一步: 导入静态 android.Manifest.permission.CALL_PHONE;

步骤 2:Where 您的点击按钮:

            Intent callIntent = new Intent(Intent.ACTION_CALL);
            callIntent.setData(Uri.parse("tel:" +driver_no ));

            if (ContextCompat.checkSelfPermission(getActivity(), CALL_PHONE) == PackageManager.PERMISSION_GRANTED) {
                startActivity(callIntent);
            } else {
                requestPermissions(new String[]{CALL_PHONE}, 1);
            }

[或者] 你在 activity 中使用 class 表示将 getActivity 更改为 getApplicationContext()

仅供参考:如果您的目标是 Android 11,则需要在清单中为 Intent.ACTION_DIAL 添加 Intent Query 元素。
