[游戏开发]安卓启动第三方程序，及接收第三方程序参数

?一、启动其他程序代码

Intent intent = new Intent();
intent.setClassName(packageName, activityName); // 指定应用包名和activity名
intent.putExtra("stringData", "我传送的内容");
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(intent); // 正常还要检测是否安装这个程序

二、接收参数代码

Intent intent = getIntent();
// String data = intent.getStringExtra("patientName"); // 获取指定字段
Bundle bundle = intent.getExtras(); // 获取所有参数
String name=bundle.getString("patientName");
if(name!=null){
   Log.e("唤醒参数1", name);
}

所有代码

public class MainActivity extends AppCompatActivity {

    String packageName="com.xxx"; // 你要启动包名
    String activityName="com.xxx.MainActivity"; // 指定到具体的activity
    public Context activityCont;
    String SelfTag="Demo————————————————————";

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        activityCont=this;
        
        // 检测接收参数
        Intent intent = getIntent();
        // String data = intent.getStringExtra("patientName"); // 获取指定字段
        Bundle bundle = intent.getExtras(); // 获取所有参数
        String name=bundle.getString("patientName");
        if(name!=null){
           Log.e("唤醒参数1", name);
        }

        // register click event
        Button button = (Button) this.findViewById(R.id.startButton);
        button.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                if(isAppInstalled(activityCont,packageName)){
                    startTDMS();
                }else{
                    Toast.makeText(activityCont, "应用程序未安装", Toast.LENGTH_SHORT).show();
                    Log.i(SelfTag,"应用程序未安装");
                }
            }
        });
    }

    // to start Applications
    public void startTDMS(){
        Intent intent = new Intent();
        intent.setClassName(packageName, activityName);
        intent.putExtra("stringData", "我传送的内容");
        intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        startActivity(intent);
    }

    // check Applications is installed
    private boolean isAppInstalled(Context context, String pgName){
        PackageInfo packageInfo;
        try {
            packageInfo = context.getPackageManager().getPackageInfo(pgName, 0);
        }catch (PackageManager.NameNotFoundException e) {
            packageInfo = null;
//            e.printStackTrace();
        }
        return packageInfo!=null;
    }



    // other way，you can ignore
    public void sameWayStartTDMS(){
        Intent intent = new Intent();
        ComponentName comp = new ComponentName(packageName, activityName);
        intent.setComponent(comp);
        int num = (int) ((Math.random() * 9 + 1) * 10);
        intent.putExtra("jsonData","NowRangeNumberIs_"+ num);
        intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        startActivity(intent);
    }


}

另：如果检测是否安装应用一直提示未安装，实际已安装，那测试手机可能是安卓11了，检测程序要加个权限
