Question

我正在尝试通过我的应用拨打电话。但是，每次崩溃时，logcat上都不会显示错误。我在清单中获得许可，并在运行时检查它。

public void call(String number){
    Intent callIntent = new Intent(Intent.ACTION_CALL);
    callIntent.setData(Uri.parse("tel:"+number));
    callIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
    context.startActivity(callIntent);

}

Answer 1

别忘了在清单中添加相关权限：

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

意图本身仅仅是描述某些内容的对象。它什么也没做。

public void call(String number){
    Intent intent = new Intent(Intent.ACTION_CALL);
    intent.setData(Uri.parse("tel:" + number));
    context.startActivity(intent);
   }

您确定上下文不为null吗？你应该做这样的事情。在通话活动中进行这些更改

private static final int REQUEST_CALL_PHONE_PERMISSION  =  100;


    if( isCallPhonePermissionGranted() ){
        call("<Number>");
    } else {
        call("<Number>");
    }

private void requestCallPermission（）{ 最终的String []权限=新的String [] {Manifest.permission.CALL_PHONE}; ActivityCompat.requestPermissions（this，权限，REQUEST_CALL_PHONE_PERMISSION）; }

   private boolean isCallPhonePermissionGranted() {
        return ActivityCompat.checkSelfPermission(this, Manifest.permission.CALL_PHONE) 
        == PackageManager.PERMISSION_GRANTED;
     }


    @Override
    public void onRequestPermissionsResult(int requestCode, @NonNull String[] 
           permissions, @NonNull int[] grantResults) {
             if (requestCode != REQUEST_CALL_PHONE_PERMISSION) {
                super.onRequestPermissionsResult(requestCode, permissions, 
                grantResults);
               return;
              }

         if (grantResults.length != 0 && grantResults[0] == 
                   PackageManager.PERMISSION_GRANTED) {
                   call("<Number>");
              return;
         }
   }


      public void call(String number){
         Intent callIntent = new Intent(Intent.ACTION_CALL);
         callIntent.setData(Uri.parse("tel:"+number));
         callIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
         context.startActivity(callIntent);
      }

最后将此权限添加到Android Manifest.xml

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

android android.intent.action.call崩溃的Android应用程序？
