I have downloaded and installed an app from Android Market. Now I want to know how to update this apk installed in my device. Is this app updated by Android Market? Will it update automatically or do I need to update it manually?
Market > My App > (an app) > [check] allow automatic updating
Android Market APKs are monitored, and you'll be notified when an update is available. There should also be a checkbox on the Market page for each of them allowing you to specify automatic updating; the developer has a case-by-case override for that for when it might lead to loss of data.
Open the Play Store App and select "Update All" to do it manually should you so desire.
There are 3 ways to update from the app store :
1. Update Manually
You can just search your app and if there is an update, there will be an
Update button to click. It will download your file and install it automatically.
2. Automatic Update
This option will update all app that doesn't need extra permissions.
To simply turn on automatic update, just tap the three bars on the left of the search box, scroll down and hit the
You'll see a lot of option that you can enable / disable. To enable the automatic update, select
Auto-update apps and select what criteria the phone must reach when the update begins.
3. Update all apps at the same time
This option will update all the app in one time. This option will ask you about extra permission that your apps need.
To update all, just slide your finger from the very left of the screen to the middle and hit
My apps. From there, you should see
Update all button if there is 2 or more update available for download.
