Android APP唤醒打开其他APP

App(a):判断是否为App(b)是否存在，不存在选择下载 存在后台状态直接唤醒 否则直接打开
App(a)部分代码

if (checkPackage("com.xxx.android")) {
				if (ToolsUtils.isBackgroundRunning(this, "com.xxx.android")) {
					Intent intent = new Intent();
					intent.setPackage("com.xxx.android");
					intent.setAction("com.xxx.android.open");
					sendBroadcast(intent);
				} else {
					PackageManager packageManager = getPackageManager();
					Intent intent = new Intent();
					intent = packageManager
							.getLaunchIntentForPackage("com.xxx.android");
					startActivity(intent);
				}
			} else {
				Toast.makeText(this, "点击下载app", Toast.LENGTH_SHORT).show();
			}

App(b)部分代码 通过广播唤醒app

            <intent-filter>
                <action android:name="com.eqiyun.android.open" />
