测试环境：自己编译的Android8.1系统（userDebug模式）

首先目标应用的AndroidManifest.xml中定义Activity的时候，必须设置一个intent-filter以及action属性，如下：

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.zht.car.aidlclient">

    <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:roundIcon="@mipmap/ic_launcher_round"
        android:supportsRtl="true"
        android:theme="@style/AppTheme">
        <activity android:name=".Test2Activity">
            <intent-filter>
                <action android:name="action_abc" />
                <category android:name="abc" />
            </intent-filter>
        </activity>
        <activity android:name=".Test1Activity">
            <intent-filter>
                <action android:name="action_abc" />
                <category android:name="abc" />
            </intent-filter>
        </activity>
        <activity android:name=".MainActivity">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>

</manifest>

<?xml version="1.0" encoding="utf-8"?>

<manifest xmlns:android="http://schemas.android.com/apk/res/android"

package="com.zht.car.aidlclient">

<application

android:allowBackup="true"

android:icon="@mipmap/ic_launcher"

android:label="@string/app_name"

android:roundIcon="@mipmap/ic_launcher_round"

android:supportsRtl="true"

android:theme="@style/AppTheme">

<intent-filter>

</intent-filter>

</activity>

<intent-filter>

</intent-filter>

</activity>

<intent-filter>

</intent-filter>

</activity>

</application>

</manifest>

上面的代码Test1Activity和Test2Activity都有一个intent-filter属性，以及他下面的action子属性

然后使用下面的代码就可以获取这个应用中的有action=”action_abc”的activity了。

        Intent intent = new Intent("action_abc");
        intent.setPackage("com.zht.xxx.xxxxxxxx"); //此处为目标应用的包名

        PackageManager pm = getPackageManager();
        List<ResolveInfo> alist = pm.queryIntentActivities(intent, PackageManager.MATCH_ALL);
        for(int i = 0; i < alist.size(); i++){
            Log.d(LOG_TAG, "queryIntentActivities: " + alist.get(i).activityInfo.name);
            Log.d(LOG_TAG, "LaunchMode: "  + alist.get(i).activityInfo.launchMode);
            Log.d(LOG_TAG, "processName: "  + alist.get(i).activityInfo.processName);
        }

Intent intent = new Intent("action_abc");

intent.setPackage("com.zht.xxx.xxxxxxxx"); //此处为目标应用的包名

PackageManager pm = getPackageManager();

List<ResolveInfo> alist = pm.queryIntentActivities(intent, PackageManager.MATCH_ALL);

for(int i = 0; i < alist.size(); i++){

Log.d(LOG_TAG, "queryIntentActivities: " + alist.get(i).activityInfo.name);

Log.d(LOG_TAG, "LaunchMode: " + alist.get(i).activityInfo.launchMode);

Log.d(LOG_TAG, "processName: " + alist.get(i).activityInfo.processName);

}
