In this case, you had to swipe down from the center of the panel to unlock the device, while swiping left or right would mute the smartphone or open the Phone app. There was also integrated flash support for the camera, an improved virtual keyboard, digital zoom, Bluetooth 2.1 technology and HTML5 support for the browser.
This update to Android 2.2 (it went up to 2.2.3), was called Froyo. This version came with a quite remarkable change in terms of operating system performance. Basically, because it started to use the Dalvik JIT compiler, with which java bytecode was converted into native language in real time.
So there was a remarkable update of the smartphone software. In addition, the speed of the applications installed on the devices was increased. And not only this, but it started to include improved app launchers with shortcuts to these, the Wi-Fi Hotspot function and tethering via USB, or support for installing apps on the external memory.
Measures in android studio
Those of us who have been with Android since the beginning have observed how the initial drawbacks with this system became a stigma. We all know most of those problems, we have had to fight against them. Some of them are still present, but most of them have been overcome, and what myths does Android still have? I have proposed to highlight ten, many of which are used by the same users of this system.Are they currently false or would serve as a summary of our system?
I start strong, that this topic particularly irritates me. Why does it have to be better a mobile where the manufacturer obviates the differentiation in software? I will not deny that there are layers and layers, but attacking them by system implies disregarding the value they bring some with their presence.I agree that the Nexus 4 and 5 moved Android much better than more powerful smartphones with manufacturer layer (TouchWiz, you touched you). In addition, once Material Design entered fully Android became even pretty.Result? The established idea that any phone that doesn’t come with Android Stock is not worth it.
Android screen densities
Declares a broadcast receiver (a BroadcastReceiver subclass) as one of the application components. Broadcast receivers allow applications to receive intents broadcast by the system and other applications, even when other components of the application are not running.
There are two ways to make a broadcast listener known to the system: one is to declare it in the manifest file with this element. The other is to create the receiver dynamically in the code and register it with the Context.registerReceiver() method. For more information on how to create receivers dynamically, see the description of the BroadcastReceiver class.
The <application> element has its own enabled attribute that applies to all application components, including broadcast receivers. The <application> and <receiver> attributes must be «true» for the broadcast receiver to be enabled. If either is «false», it is disabled and cannot be created.
If not specified, the default value depends on whether the broadcast receiver contains intent filters. If the receiving app contains at least one intent filter, the default value is «true». Otherwise, the default value is «false».
Android for everyone
You must specify each function in a separate <uses-feature> element. Therefore, if your application requires multiple functions, you must declare multiple <uses-feature> elements. For example, an application that requires Bluetooth and camera functions on the device must declare these two elements:
For some functions, there might be a specific attribute that allows you to define a version of the function, such as the version of Open GL that was used (declared with glEsVersion). Other functions that do or do not exist on a device, such as the camera, are declared with the name attribute.
Although the <uses-feature> element is only enabled for devices with API level 4 or higher, it includes these elements for all applications, even if minSdkVersion is version «3» or earlier. Devices with earlier versions of the platform simply ignore the element.
Note: When declaring a feature, remember to also request the necessary permissions. For example, you must not fail to request the CAMERA permission so that your application can access the camera API. Requesting the permission authorizes your application to access the corresponding hardware and software. Declaring the functions used by your application ensures proper compatibility with the device.
