判断用户是否开启某个服务

  public static boolean serviceIsStart(Context cont, String className) {
        ActivityManager mActivityManager = (ActivityManager) cont
                .getSystemService(cont.ACTIVITY_SERVICE);
        List<ActivityManager.RunningServiceInfo> mServiceList = mActivityManager
                .getRunningServices(30);
        for (int i = 0; i < mServiceList.size(); i++) {
            if (className.equals(mServiceList.get(i).service.getClassName())) {
                return true;
            }
        }
        return false;
    }

判断是否安装了某个软件 

    public static boolean isInstall(Context cont, String packName) {
        PackageManager packageManager = cont.getPackageManager();
        List<PackageInfo> list = packageManager
                .getInstalledPackages(PackageManager.GET_PERMISSIONS);
        for (PackageInfo packageInfo : list) {
            if (packageInfo.packageName.equals(packName)) {
                return true;
            }
        }
        return false;
    }

获取手机串号唯一标示 

	public static String getMIEI(Context context) {
		String MIEI;
		TelephonyManager telephonemanage = (TelephonyManager) context
				.getSystemService(Context.TELEPHONY_SERVICE);
		try {
			MIEI = telephonemanage.getDeviceId();
			return MIEI;
		} catch (Exception e) {
			Log.i("error", e.getMessage());
			return null;
		}
	}

获取版本 

	public static int getVersionCode(Context context) throws Exception {
		PackageManager packageManager = context.getPackageManager();
		PackageInfo packInfo = packageManager.getPackageInfo(
				context.getPackageName(), 0);
		int version = packInfo.versionCode;
		return version;
	}

获取手机内所有应用 

	public static List<PackageInfo> getAllApps(Context context) {
		List<PackageInfo> apps = new ArrayList<PackageInfo>();
		PackageManager pManager = context.getPackageManager();
		// 获取手机内所有应用
		List<PackageInfo> paklist = pManager.getInstalledPackages(0);
		for (int i = 0; i < paklist.size(); i++) {
			PackageInfo pak = (PackageInfo) paklist.get(i);
			// 判断是否为非系统预装的应用程序
			if ((pak.applicationInfo.flags & pak.applicationInfo.FLAG_SYSTEM) <= 0) {
				// customs applications
				apps.add(pak);
			}
		}
		return apps;
	}

通过包名获取Apk名字 

	public static String getApkName(Context context, String packeName) {
		PackageManager pManager = context.getPackageManager();
		List<PackageInfo> appList = getAllApps(context);

		for (int i = 0; i < appList.size(); i++) {
			if (appList.get(i).packageName.equals(packeName)) {
				return pManager.getApplicationLabel(
						appList.get(i).applicationInfo).toString();
			}
		}
		return null;
	}

判断手机GPS是否开启 

<span style="white-space:pre">	</span>public static boolean gpsIsOpen(Context context) {
		LocationManager alm = (LocationManager) context.getSystemService(Context.LOCATION_SERVICE);
		if (alm.isProviderEnabled(android.location.LocationManager.GPS_PROVIDER)) {
			return true;
		}
		return false;
	}

判断是手机品牌 

	public static boolean isHTC() {
		String MODEL = android.os.Build.MODEL;
		if (MODEL.contains("HTC")) {
			return true;
		} else
			return false;
	}

设置手机系统亮度 

	public static void setSystemLight(Activity activity, int light) {
		ContentResolver cr = activity.getContentResolver();
		Settings.System.putInt(cr, "screen_brightness", light);
		Window window = activity.getWindow();
		LayoutParams attributes = window.getAttributes();
		float flevel = light;
		attributes.screenBrightness = flevel / 255;
		float x = attributes.screenBrightness;
		activity.getWindow().setAttributes(attributes);
	}
