android 通过 包名启动Activity

最近因为项目需要，不让app在应用列表显示，只能用自己的启动器启动。基本搞定，效果实现了，不过与我的计划相差挺远的。

private void RunApp(String packageName) {

PackageInfo pi;

try {

pi = getPackageManager().getPackageInfo(packageName, 0);

Intent resolveIntent = new Intent(Intent.ACTION_MAIN, null);

// resolveIntent.addCategory(Intent.CATEGORY_LAUNCHER);

resolveIntent.setPackage(pi.packageName);

PackageManager pManager = getPackageManager();

List<ResolveInfo> apps = pManager.queryIntentActivities(

resolveIntent, 0);

ResolveInfo ri = apps.iterator().next();

if (ri != null) {

packageName = ri.activityInfo.packageName;

String className = ri.activityInfo.name;

Intent intent = new Intent(Intent.ACTION_MAIN);

// intent.addCategory(Intent.CATEGORY_LAUNCHER);

ComponentName cn = new ComponentName(packageName, className);

intent.setComponent(cn);

startActivity(intent);

}

} catch (NameNotFoundException e) {

// TODO Auto-generated catch block

e.printStackTrace();

}

}
