MSG 12-13 拦截物理返回键跳到桌面
@Override

//隐式意图跳到桌面

startActivity(intent);
finish();

MSG 12-14 验证密码&通过自定义广播传递数据
btOk.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
String pwd = etPwd.getText().toString().trim();
if (!TextUtils.isEmpty(pwd)) {
if (pwd.equals("123")) {
finish();
}
}
}
});
结束后，在服务中还会开启，所以需要从activity传递给服务
//发送自定义广播，传递数据
Intent intent = new Intent();
intent.setAction("action_skip_package");
intent.putExtra("packageName", packageName);
sendBroadcast(intent);

if (isExist && !packageName.equals(packageName)) {
Intent intent = new Intent(this, AppGraLockActivity.class);
intent.putExtra("packageName", packageName);
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(intent);
}
}
