android判断某服务是否正在运行

android判断某服务是否正在运行

Android系统中，判断应用服务是否启动有两种方式：
1.根据包名判断,以下为判断代码：
public boolean checkApkExist(Context context, String packageName) {
if (packageName == null || “”.equals(packageName))
return false;
try {
ApplicationInfo info = context.getPackageManager()
.getApplicationInfo(packageName,
PackageManager.GET_UNINSTALLED_PACKAGES);
return true;
} catch (NameNotFoundException e) {
return false;
}
}

2. 根据Intent判断，以下为判断代码：
public boolean checkApkExist(Context context, Intent intent) {
List list = context.getPackageManager().queryIntentActivities(intent, 0);
if(list.size() > 0){
return true;
}
return false;
}
public boolean checkApkExist(Context context, String packageName) {
if (packageName == null || “”.equals(packageName)) return false;
try {
ApplicationInfo info = context.getPackageManager() .getApplicationInfo(packageName, PackageManager.GET_UNINSTALLED_PACKAGES); return true;
} catch (NameNotFoundException e) { return false; }
}
public boolean checkApkExist(Context context, Intent intent) {
List list = context.getPackageManager()
.queryIntentActivities(intent, 0);
if (list.size() > 0) {
return true;
}
return false;
}

public static boolean isrunning(context context,string packagename){ activitymanager am = (activitymanager) context.getsystemservice(activity_service); list infos = am.getrunningappprocesses(); for(runningappprocessinfo rapi : infos){ if(rapi.processname.equals(packagename)) return true; } return false; }
