使用自定義意圖拋出來啟動活動未發現異常

Question

我正在使用以下代碼從應用程序啟動活動：

Intent intent = new Intent();
intent.setAction("com.android.excample.cutstom_action");
intent.setData(data); //public Uri data
intent.putExtra(Intent.Extra_stream, stream); // public Uri stream
startActivity(intent);

在另一個應用程序中，活動在清單文件中定義如下：

<activity android:name="MyActivity">
<intent-filter>
<action android:name="com.android.excample.cutstom_action"/>
<category android:name = "android.intent.category.DEFAULT"/>
<data android:mimeType="*/*"/>
</intent-filter>
</activity>

但是當我嘗試開始活動時，我發現活動未發現異常。 請幫我解決這個問題

Answer 1

設置“。” 在manifast文件中您的活動名稱之前

".MyActivity"

或使用完全限定的路徑設置它，如下所示：

"com.android.excample.MyActivity"
