Android短信管理器獲取錯誤

Question

我想發送一個簡單的短信。 它的工作是從教程下載的樣本。 但是，當我試圖複製相同的代碼，我收到錯誤。 下面是我嘗試調試時的代碼。

D/ViewRootImpl: ViewPostImeInputStage processPointer 0 
D/ViewRootImpl: ViewPostImeInputStage processPointer 1 
W/System.err: java.lang.SecurityException: Sending SMS message: uid 10333 does not have android.permission.SEND_SMS.

W/System.err:  at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:1120) 
Disconnected from the target VM, address: 'localhost:8616', transport: 'socket' 

我試圖通過連接一個實際的手機和權限錯誤可能是從上面明顯的一個調試實際上已經在Android清單文件中定義。

我的MainActivity如下

public class MainActivity extends AppCompatActivity { 

    Button buttonSend; 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_main); 




     buttonSend = (Button) findViewById(R.id.buttonSend); 

     buttonSend.setOnClickListener(new View.OnClickListener() { 

      @Override 
      public void onClick(View v) { 



       try { 

        /* Intent sendIntent = new Intent(Intent.ACTION_VIEW); 
        sendIntent.putExtra("sms_body", "default content"); 
        sendIntent.setType("vnd.android-dir/mms-sms"); 
        startActivity(sendIntent);*/ 

        SmsManager smsManager = SmsManager.getDefault(); 
        smsManager.sendTextMessage("91195525", null, "Test", null, null); 
        Toast.makeText(getApplicationContext(), "SMS Sent!", 
          Toast.LENGTH_LONG).show(); 


       } catch (Exception e) { 
        Toast.makeText(getApplicationContext(), 
          "SMS faild, please try again later SMS!", 
          Toast.LENGTH_LONG).show(); 
        e.printStackTrace(); 
       } 

      } 
     }); 


    } 
} 

我的Android清單文件

<?xml version="1.0" encoding="utf-8"?> 
<manifest xmlns:android="http://schemas.android.com/apk/res/android" 
    package="com.creations.oreo.valletcall"> 

    <uses-sdk 
     android:minSdkVersion="8" 
     android:targetSdkVersion="18" /> 
    <uses-permission android:name="android.permission.SEND_SMS"/> 

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



    <application 
     android:allowBackup="true" 
     android:icon="@mipmap/ic_launcher" 
     android:label="@string/app_name" 
     android:supportsRtl="true" 
     android:theme="@style/AppTheme"> 
     <activity android:name=".MainActivity"> 
      <intent-filter> 
       <action android:name="android.intent.action.MAIN" /> 

       <category android:name="android.intent.category.LAUNCHER" /> 
      </intent-filter> 
     </activity> 
    </application> 

</manifest> 

例如，該教程中，我以下是本

Answer 1

指the official doc

// Here, thisActivity is the current activity 
if (ContextCompat.checkSelfPermission(thisActivity, 
       Manifest.permission.SEND_SMS) 
     != PackageManager.PERMISSION_GRANTED) { 

    // Should we show an explanation? 
    if (ActivityCompat.shouldShowRequestPermissionRationale(thisActivity, 
      Manifest.permission.SEND_SMS)) { 

     // Show an explanation to the user *asynchronously* -- don't block 
     // this thread waiting for the user's response! After the user 
     // sees the explanation, try again to request the permission. 

    } else { 

     // No explanation needed, we can request the permission. 

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

     // MY_PERMISSIONS_REQUEST_READ_CONTACTS is an 
     // app-defined int constant. The callback method gets the 
     // result of the request. 
    } 
} 

你可以閱讀

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

       // permission was granted, yay! Do the 
       // contacts-related task you need to do. 

      } 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 
    } 
} 

這樣，你所要求的權限運行的結果，現在你得implmeent這些方法，使他們在您的應用程序工作。

希望這會有所幫助。
