android - 我怎样才能对图书馆的 Activity 做出 Intent ？

Question

我创建了一个库项目，然后构建它，获取 .aar 并解压缩它。获取包含库的 classes.jar 文件，并将其添加到另一个项目中。该项目识别我的文件，我可以从中调用方法和函数。我的问题是我尝试从我的库中调用一个 Activity 的 Intent ，如下所示:

 textView = (TextView) findViewById(R.id.text);
    textView.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            Intent intent = new Intent(MainActivity.this, InCallActivity.class);
            intent.putExtra("duration",20);
            intent.putExtra("message","test");
            intent.putExtra("url","https://facetalk.vidyo-nl.com/mobile.html?roomdirect.html&key=QMvMp3eKTqOeLAWQ6HOvHqFJd0");
            intent.putExtra("test","true");
            startActivity(intent);
        }
    });

但是我遇到这样的问题:

现在我发现了一些关于需要在 project.properties 文件中设置的 list 合并 manifestmerger.enabled=true 的内容。但是我正在使用 AndroidStudio，而不是 Eclipse，因此我没有那个文件。我该如何解决这个问题？

Answer 1

<activity
    android:name=".MainActivity">
       <intent-filter>
            <action android:name="com.example.main.mainactivity" />
           <category android:name="android.intent.category.DEFAULT" />
      </intent-filter>
</activity>

在你的库中只需调用它来打开 MainActivity:

Intent intent = new Intent("com.example.main.mainactivity");
startActivity(intent);
