SecurityException：Permission Denial：启动Intent

Question

我已经发布了应用程序，主要任务是将意图转发给其他应用程序。有些用户在向Google + app发送任何内容时都会遇到奇怪的错误：

 java.lang.SecurityException: Permission Denial: starting Intent { act=android.intent.action.SEND typ=image/jpeg flg=0x3000000 cmp=com.google.android.apps.plus/.phone.PostActivity (has extras) } from ProcessRecord{409b7828 14815:com.andmadesoft.share/10128} (pid=14815, uid=10128) requires null

我无法在任何测试手机上重现错误。希望任何人都可以帮我解决这个错误。

在ShareIntentResolver活动中发送代码部分：

...
Context cont;

protected void onCreate(Bundle savedInstanceState, CharSequence title, Intent target, ArrayList<Intent> extraIntents) {
        super.onCreate(savedInstanceState);
        cont = this;
...

private void resolveIntent(IntentInfo ii){
        ii.sendIntent(cont);  // error is got here
}

IntentInfo类：

public void sendIntent(Context context) {
        context.startActivity(intent); //intent is just any intent that I am forwarding
}
