Android APP喚醒打開其他APP

App(a):判斷是否為App(b)是否存在，不存在選擇下載 存在后台狀態直接喚醒 否則直接打開
App(a)部分代碼

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, "點擊下載app", Toast.LENGTH_SHORT).show();
			}
