Android在应用中依据包名启动另外一个APP

以下为TestIntentData工程

MainActivity如下:

[java]
package cn.testintentdata;
import java.util.List;
import android.net.Uri;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.app.Activity;
import android.content.ComponentName;
import android.content.Intent;
import android.content.pm.PackageInfo;
import android.content.pm.PackageManager.NameNotFoundException;
import android.content.pm.ResolveInfo;

public class MainActivity extends Activity {
    private Button mButton;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        init();
    }
    private void init(){
        mButton=(Button) findViewById(R.id.button);
        mButton.setOnClickListener(new OnClickListener() {
            @Override
            public void onClick(View view) {
                startAnotherApp("cc.testintent");
            }
        });
    }

    private void startAnotherApp(String packageName){
        PackageInfo packageInfo = null;
        try {
            packageInfo = getPackageManager().getPackageInfo(packageName, 0);
            if (packageInfo==null) {

            }
        } catch (NameNotFoundException e) {
            e.printStackTrace();
        }


        //<data android:scheme="app" android:host="jp.co.cybird.barcodefootballer/" />


        Intent resolveIntent = new Intent(Intent.ACTION_MAIN, null);
        resolveIntent.setData(Uri.parse("app://jp.co.cybird.barcodefootballer/"));

        getPackageManager().queryIntentActivities(resolveIntent, 0);

        System.out.println("resolveInfoList.size()="+resolveInfoList.size());

        ResolveInfo resolveInfo = resolveInfoList.iterator().next();
        if (resolveInfo != null ) {
            String activityPackageName = resolveInfo.activityInfo.packageName;

            intent.setComponent(componentName);
            startActivity(intent);
        }

    }
