Android 与 ChooserActivity 崩溃

Question

我在后台线程中对数据进行了一些操作，然后我想要求用户选择相应的 Activity 来处理结果:

Intent chooserIntent = Intent.createChooser( intent, getString( R.string.select_application_for, intent.getData() ) );
chooserIntent.putExtra( Intent.EXTRA_INITIAL_INTENTS, intents.toArray( new Parcelable[ intents.size() ] ) );
startActivity( chooserIntent );

但是我总是在使用下一个 StackTrace 时崩溃:

android.app.SuperNotCalledException: Activity {android/com.android.internal.app.ChooserActivity} did not call through to super.onCreate()
at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:2025)

如果我注释行:

chooserIntent.putExtra( Intent.EXTRA_INITIAL_INTENTS, intents.toArray( new Parcelable[ intents.size() ] ) );

crash消失了，但这不是我想要的。

我想知道是否有人已经解决了这个难题。

问题已在以下评论中解决:

从源代码来看，看起来 !(pa[i] instanceof Intent) 正在针对您的一个或多个 Intent 评估为真，pa 是 intents.toArray( new Parcelable[ intents.size() ] )。您能否使用 Log 语句来确认 Intent 中的项目确实通过了 intents.get(i) instanceof Intent？

来源:

public class  [More ...] ChooserActivity extends ResolverActivity {
    @Override
    protected void  [More ...] onCreate(Bundle savedInstanceState) {

    ....
    ....

    Parcelable[] pa = intent.getParcelableArrayExtra(Intent.EXTRA_INITIAL_INTENTS);
        Intent[] initialIntents = null;
        if (pa != null) {
            initialIntents = new Intent[pa.length];
            for (int i=0; i<pa.length; i++) {

                // The check for if-statement is evaluating to `true`
                if (!(pa[i] instanceof Intent)) {
                    Log.w("ChooseActivity", "Initial intent #" + i
                        + " not an Intent: " + pa[i]);
                    finish();
                    return;
                }
                initialIntents[i] = (Intent)pa[i];
            }
        }
        super.onCreate(savedInstanceState, target, title, initialIntents, false);
    }
