if (packageInfo.packageName.equals(packName)) {

return true;

}

return false;

public static String getMIEI(Context context) {

String MIEI;

TelephonyManager telephonemanage &＃61; (TelephonyManager) context

.getSystemService(Context.TELEPHONY_SERVICE);

try {

MIEI &＃61; 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 &＃61; context.getPackageManager();

int version &＃61; packInfo.versionCode;

for (int i &＃61; 0; i

PackageInfo pak &＃61; (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) <&＃61; 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 &＃61; context.getPackageManager();

List appList &＃61; getAllApps(context);

for (int i &＃61; 0; 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

public static boolean gpsIsOpen(Context context) {

public static void setSystemLight(Activity activity, int light) {

ContentResolver cr &＃61; activity.getContentResolver();

Settings.System.putInt(cr, "screen_brightness", light);

Window window &＃61; activity.getWindow();

LayoutParams attributes &＃61; window.getAttributes();

float flevel &＃61; light;

attributes.screenBrightness &＃61; flevel / 255;

float x &＃61; attributes.screenBrightness;

activity.getWindow().setAttributes(attributes);
