Question

我希望将项目A调用到项目B，但是在项目B中，将项目C用于库。

我使用了项目A中的代码

intent = new Intent("com.example.projectb.reading");
        startActivity(intent);

项目B中的

和AndroidManifest

<activity 
        android:name="com.example.projectb.reading" 
        android:label="Trainee" 
        android:screenOrientation="portrait">
        <intent-filter>
            <action android:name="com.xample.projecta.cls_show" />
            <category android:name="android.intent.category.DEFAULT" />
        </intent-filter>
        </activity>

但是我的logcat已经

了

请帮助我，问题在哪里。

Answer 1

从stackoverflow中引用这两个链接。它会帮助你

How to call activity of one project from activity of another project in android?Also vice versa?

2。 How to call an activity in another project?

Answer 2

变化

   intent = new Intent("com.example.projectb.reading");
    startActivity(intent);

到

    intent = new Intent("com.xample.projecta.cls_show");
    startActivity(intent);

Answer 3

您使用的是错误的构造函数

intent = new Intent(this, "com.example.projectb.reading");
        startActivity(intent);

阅读intent了解详情。

Answer 4

您可以通过Intent-filter实现这一目标。

FirstActivity

Intent intent = new Intent("com.example.secondapp.SecondActivity");
startActivity(intent);

SecondActivity - AndroidManifest.xml

    <activity
        android:name="com.example.secondapp.SecondActivity"
        android:label="@string/app_name" >
        <intent-filter>
            <action android:name="com.example.secondapp.SecondActivity" />
            <category android:name="android.intent.category.DEFAULT" />
        </intent-filter>
    </activity>
