You will notice a warning that will tell you that all data will be deleted. Press Ok to confirm and then open the Play Store to look for the app and begin the download. Check if this helps you fix the problem on your Android device. Google Play Services is the process through which your applications communicate with various sections of your device.
It enables sync and ensures that push notifications are sent to the device apps on time. Google Play Services plays an essential role in the working of applications. A problem in the cache or data files of the Play Services can cause a problem when it comes to downloading the applications from the Play Store.
Once the cache files have been wiped, check if the problem is fixed. If you can still download apps from the Play Store, then follow the same steps to return to the screen from where you cleared the cache.
This time, you must tap on Clear Data to delete the data. You will notice a warning on your screen. Tap on OK to confirm deleting the data. The data synchronization of your device that allows the syncing of data can help you solve the problem. Several readers found this to be an easy way of resolving their apps not downloading from the Play Store. Once you have completed this step, go back into Google Play Store and check if the app is being downloaded now. Once the new updates are installed, your device will automatically restart.
After the restart, check if the apps are being downloaded to your device now. Resetting the Google Account can help you solve the problem of your Android not downloading the apps. When you reset the account, you will be deleting the entire account and starting all over again. It means you should know your Google Account username and password. If you do not have these details, then you will not be able to add the account back to your device again. The Google account will be removed entirely from your device, and it will be added all over again.
If you have more than one Google accounts on your device, then make sure you remove all the Google account. After deleting the accounts, you will have to start entering the accounts once again into your device. Go back to the Settings menu of your device and tap on Accounts once again.
Now you will find the option to Add Account. Tap on Add Account and complete the process of adding the account to your device. You must follow these steps to add all your Google accounts, and once this is done, return to the Play Store and find out if this has resolved your problem.
Sometimes, your Play Store updates may be the cause of the problem. So, uninstall the update and allow the app to update once again. A visual representation of the important parts of a cold application launch. When your application launches, the blank starting window remains on the screen until the system finishes drawing the app for the first time. At that point, the system process swaps out the starting window for your app, allowing the user to start interacting with the app.
Afterwards, the app spawns the main thread, also known as the UI thread, and tasks it with creating your main activity. From this point, system- and app-level processes proceed in accordance with the app lifecycle stages. Typically, the onCreate method has the greatest impact on load time, because it performs the work with the highest overhead: loading and inflating views, and initializing the objects needed for the activity to run.
A hot start of your application is much simpler and lower-overhead than a cold start. In a hot start, all the system does is bring your activity to the foreground. However, if some memory has been purged in response to memory trimming events, such as onTrimMemory , then those objects will need to be recreated in response to the hot start event. A hot start displays the same on-screen behavior as a cold start scenario: The system process displays a blank screen until the app has finished rendering the activity.
A warm start encompasses some subset of the operations that take place during a cold start; at the same time, it represents more overhead than a hot start.
There are many potential states that could be considered warm starts. For instance:. Android provides several means of letting you know that your app has a problem, and to help you diagnose it. Android vitals can alert you that the problem is occurring, and diagnostic tools can help you diagnose the problem. Android vitals can help improve your app's performance by alerting you, via the Play Console , when your app's startup times are excessive. Android vitals considers your app's startup times excessive when the app's:.
Android vitals doesn't report data for hot startups. In order to properly diagnose start time performance, you can track metrics that show how long it takes your application to start. In Android 4. This value represents the amount of time elapsed between launching the process and finishing drawing the corresponding activity on the screen. The elapsed time encompasses the following sequence of events:. To find elapsed time in Android Studio, you must disable filters in your logcat view.
Disabling the filters is necessary because the system server, not the app itself, serves this log. Figure 2 shows how to disable filters, and, in the second line of output from the bottom, an example of logcat output of the Displayed time. Figure 2. Disabling filters, and finding the Displayed value in logcat. The Displayed metric in the logcat output does not necessarily capture the amount of time until all resources are loaded and displayed: it leaves out resources that are not referenced in the layout file or that the app creates as part of object initialization.
Sometimes the Displayed line in the logcat output contains an additional field for total time. For example:. In this case, the first time measurement is only for the activity that was first drawn. The total time measurement begins at the app process start, and could include another activity that was started first but did not display anything to the screen. The total time measurement is only shown when there is a difference between the single activity and total startup times.
Here's an example:. You can use the reportFullyDrawn method to measure the elapsed time between application launch and complete display of all resources and view hierarchies. This can be valuable in cases where an app performs lazy loading.
In lazy loading, an app does not block the initial drawing of the window, but instead asynchronously loads resources and updates the view hierarchy. To address this concern, you can manually call reportFullyDrawn to let the system know that your activity is finished with its lazy loading. When you use this method, the value that logcat displays is the time elapsed from the creation of the application object to the moment reportFullyDrawn is called.
Here's an example of the logcat output:. The logcat output sometimes includes a total time, as discussed in Time to initial display. To learn about inline tracing, see the documentation for the Trace functions, and the overview of system tracing. These issues chiefly concern initializing app and activity objects, as well as the loading of screens.
Launch performance can suffer when your code overrides the Application object, and executes heavy work or complex logic when initializing that object. Some initializations may be completely unnecessary: for example, initializing state information for the main activity, when the app has actually started up in response to an intent. With an intent, the app uses only a subset of the previously initialized state data.
Garbage collection is especially a consideration with the Dalvik runtime; the Art runtime performs garbage collection concurrently, minimizing that operation's impact. If the tool shows that these methods are taking a long time to finish executing, you should explore further to see what work is occurring there.
In other words, you should only initialize objects that are immediately needed. Instead of creating global static objects, move to a singleton pattern where the app initializes objects only the first time it needs them. Also, consider using a dependency injection framework like Hilt that creates objects and dependencies when they are injected for the first time.
If your app uses content providers to initialize app components at startup, consider using the App Startup library instead. Activity creation often entails a lot of high-overhead work.
Often, there are opportunities to optimize this work to achieve performance improvements. Such common issues include:. Doing so can hide a slow activity launch. A common way to implement a themed launch screen is to use the windowDisablePreview theme attribute to turn off the initial blank screen that the system process draws when launching the app.
Also, it forces the user to wait with no feedback while the activity launches, making them wonder if the app is functioning properly. You can often diagnose this problem by observing a slow response when a user launches your app. In such a case, the screen may seem to be frozen, or to have stopped responding to input. We recommend that, rather than disabling the preview window, you follow the common Material Design patterns.
You can use the activity's windowBackground theme attribute to provide a simple custom drawable for the starting activity. So by using the above mentioned apps, you can speed your phone by making reducing the usage of your phone's ram.

May be logging can help here. Switching adapters between phones can mix-match voltage, wattage, amperage and so on. This is why it's best to stick with the adapter that came with your phone or at the very least take a look at the fine print and replace it with another adapter of the same type.
Sorry, but it's true. If you're sitting there wondering why your Galaxy S2 takes so long to charge it's probably because the old-timer is getting worn out after many years of use. Newer processors not only support fast charging, but newer phones even come with turbo charging chargers. The Galaxy S6, for example, can get your four hours' worth of usage after just ten minutes plugged in. Other phones that support fast charging will have a lightning bolt icon on the charger itself, possibly along with turbo charging output figures.
Your phone can also become a pocket lint cave too, so check your microUSB port and make sure the little flap in the port isn't bent while you're looking in there. Your battery might just be kaput too, so ask yourself how old it is. At least one advantage of older phones is the removable battery, so if you can pop it out, consider replacing it if it can never seem to charge normally. At the end of the day, entropy bring a slow but sure end to all things.
If your phone is ancient, it's time to accept that it's past its prime. It's true - you're the worst thing preventing your phone charging quickly when you can't keep your hands off it. Seriously, if time is of the essence, your best bet is to leave it alone.
