When you need to delete an app in development, you need to use the ADB uninstall command. Its explanation is as follows:
ADB uninstall [-K] ('-K' means keep the data and cache Directories)
By default, this command can run normally when o
Add the following code to the App.js page. config (function ($stateProvider, $urlRouterProvider, $ionicConfigProvider) { $ IonicConfigProvider.platform.ios.tabs.style (' standard '); $ionicConfigProvider. Platform.ios.tabs.position (' bottom '); $ionicConfigProvider. Platform.android.tabs.style (' standard '); $ionicConfigProvider. Platform.android.tabs.position (' standard '); $ionicConfigProvider. Platform.ios.navBar.alignTitle (' center '); $ionicConfigProvider.
When the app code is automatically updated, it starts with the following code Intent Intent = new Intent (Intent.action_view); Intent.setdataandtype (Uri.parse ("file://" +constants.sdk_dir+file.separator+constants.sdk_name), "application/Vnd.android.package-archive "); Context.startactivity (Intent); However, in some cases, when using these codes, when the dialog box displays the installation confirmation,
Android adds the screen saver function to the App, which is similar to the advertisement function ., Androidapp
When a friend does not perform any operation for every activity in the app for 30 seconds, a screen saver is displayed. The screen saver keeps the screen bright,

second, what is the wrong signal

In Android, the color of the status bar is the same as that of our App. androidapp
In fact, there is nothing. It is a topic. Let's look at the code below:

is really amazing!) )Anyway, it's still in the experimental phase, and some of the features are still under development. For serious users, it's best to wait until it's finally released.ConclusionI have to say that the new Gradle Build Tools are very interesting. The main changed DSL looks very promising, and has far-reaching implications for the present. Good code should tell us what it can do (translator
Otherwise, Android is especially open. In Android development, this requirement can be achieved by sending a broadcast.
Here is a piece of encapsulated code.

Native or not ·Most apps these days are written for Dalvik. When I say "Most apps" I mean "everything that isn't a game"; game developersTypically want to code in C/C ++ and that's it. dalvik offers a nice fast gateway to OpenGL and all the phone's hardware, but game Devs just don't want to hear about virtual machines, so they use the androidNdk.
