Android平台的unity应用调起另外一个应用

 bool fail = false;
 string bundleId = "com.xxxx.另外一个应用包名";
 AndroidJavaClass up = new AndroidJavaClass("com.unity3d.player.UnityPlayer");
 AndroidJavaObject ca = up.GetStatic<AndroidJavaObject>("currentActivity");
 AndroidJavaObject packageManager = ca.Call<AndroidJavaObject>("getPackageManager");
      
 AndroidJavaObject launchIntent = null;
 try
 {
     launchIntent = packageManager.Call<AndroidJavaObject>("getLaunchIntentForPackage",bundleId);
 }
 catch (System.Exception e)
 {
     fail = true;    // 应用未安装
 }
  
 if (fail)
 { 
     //跳转应用下载地址
     Application.OpenURL("www.app.com");
 }
 else
     ca.Call("startActivity",launchIntent);
  
 up.Dispose();
 ca.Dispose();
 packageManager.Dispose();
 launchIntent.Dispose();

如果要传递数据给另外一个app，调用putExtra即可

launchIntent.Call<AndroidJavaObject>("putExtra", "arguments", "aaaaaaaaaaaaaaaaa");

在被调起的应用中用getExtra得到传递过来的数据

void getExtra()
{
    string arguments = "";

    AndroidJavaClass UnityPlayer = new AndroidJavaClass("com.unity3d.player.UnityPlayer");
    AndroidJavaObject currentActivity = UnityPlayer.GetStatic<AndroidJavaObject>("currentActivity");

    AndroidJavaObject intent = currentActivity.Call<AndroidJavaObject>("getIntent");
    bool hasExtra = intent.Call<bool>("hasExtra", "arguments");

    if (hasExtra)
    {
        AndroidJavaObject extras = intent.Call<AndroidJavaObject>("getExtras");
        arguments = extras.Call<string>("getString", "arguments");
        Debug.Log(arguments);
    }
    else
    {
        Debug.Log("No auguments");
    }
}
