Android 运行时权限已授予但仍被拒绝

Question

我正在尝试编写一个发送短信的应用程序。当检查我是否拥有所需的权限时，它返回 true 但仍然因 SecurityException 而崩溃。

按下按钮时

private void startAutoMsg() {
    Log.d("Starting Auto Msg");
    //FIXME: Start proper loop
    if (canSendSms()) {
        sendMessage();
        mAutoMsgButton.setBackgroundColor(Color.GREEN);
    }
}

我正在使用以下函数来确定我是否拥有适当的权限

private boolean canSendSms() {
    if ((ContextCompat.checkSelfPermission(mContext, Manifest.permission.SEND_SMS)
            == PackageManager.PERMISSION_GRANTED)) {
        Log.d("Permission granted");
        return true;
    } else {
        Log.d("Permission denied");
        ActivityCompat.requestPermissions(
                mActivity, new String[]{Manifest.permission.SEND_SMS}, 101);
        return false;
    }
}

上面的代码返回 true，因此 SMS 试图用这个发送

private void sendMessage() {
    Log.d("sending message");
    PendingIntent sentPI = PendingIntent.getBroadcast(
            mContext, 0, new Intent(Constants.ACTION_SMS_SENT), 0);
    PendingIntent deliveredPI = PendingIntent.getBroadcast(
            mContext, 0, new Intent(Constants.ACTION_SMS_DELIVERED), 0);
    Thread thread = new Thread(new Runnable() {
        @Override
        public void run() {
            mSmsManager.sendTextMessage("mNumber", null, mText, sentPI, deliveredPI);
        }
    });
    thread.run();
}

在我的 list 中:

<uses-permission android:name="android.permission.SEND_SMS"/>
<uses-permission android:name="android.permission.READ_SMS" />
<uses-permission android:name="android.permission.WRITE_SMS" />
<uses-permission android:name="android.permission.RECEIVE_SMS" />
<uses-permission android:name="android.permission.RECEIVE_MMS" />

请这样做:

在您的应用中创建此类:

import android.content.pm.PackageManager;
import android.os.Bundle;
import android.support.annotation.Nullable;
import android.support.v4.app.ActivityCompat;
import android.support.v4.content.ContextCompat;
import android.support.v7.app.AppCompatActivity;


public abstract class RuntimePermissionsActivity extends AppCompatActivity
{


    @Override
    protected void onCreate(@Nullable Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);
    }

    @Override
    public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults)
    {
        super.onRequestPermissionsResult(requestCode, permissions, grantResults);
        int permissionCheck = PackageManager.PERMISSION_GRANTED;
        for (int permission : grantResults)
        {
            permissionCheck = permissionCheck + permission;
        }
        if ((grantResults.length > 0) && permissionCheck == PackageManager.PERMISSION_GRANTED)
        {
            onPermissionsGranted(requestCode);
        }
        else
        {
            onPermissionsDeny(requestCode);
        }
    }

    public void requestAppPermissions(final String[] requestedPermissions, final int requestCode)
    {
        int permissionCheck = PackageManager.PERMISSION_GRANTED;
        boolean shouldShowRequestPermissionRationale = false;
        for (String permission : requestedPermissions)
        {
            permissionCheck = permissionCheck + ContextCompat.checkSelfPermission(this, permission);
            shouldShowRequestPermissionRationale = shouldShowRequestPermissionRationale || ActivityCompat.shouldShowRequestPermissionRationale(this, permission);
        }
        if (permissionCheck != PackageManager.PERMISSION_GRANTED)
        {
            ActivityCompat.requestPermissions(this, requestedPermissions, requestCode);
        }
        else
        {
            onPermissionsGranted(requestCode);
        }
    }

    public abstract void onPermissionsGranted(int requestCode);
    public abstract void onPermissionsDeny(int requestCode);

}

接下来在您的 MainActivity(或任何 Activity)中，您应该像这样从此类扩展:

public class Main_Activity extends RuntimePermissionsActivity

并在您的 Activity 中覆盖此方法:

@Override
public void onPermissionsGranted(int requestCode) {

}

@Override
public void onPermissionsDeny(int requestCode) {

}

最后:使用此代码检查权限:

MainActivity.super.requestAppPermissions(new String[]{android.Manifest.permission.WRITE_EXTERNAL_STORAGE}, requestcodeWriteStorage);

你也可以检查很多权限，你应该在字符串数组中定义;

requestcodeWriteStorage 是一个整数，您应该定义它；

使用我阅读的 2 种方法管理您的回调。

例如:

@Override
public void onPermissionsGranted(int requestCode) {
    if (requestCode == requestcodeWriteStorage){
        Toast.makeText(this,"Done",Toast.LENGTH_LONG).show();

    }
