All of the phones in the tests were infected successfully by Joker — also known as Bread — malware. Every single device tested was also infected with Bluefrag, a critical vulnerability that focuses on the Bluetooth component of Android.

The watchdog also said that smartphone makers have questions to answer about the environmental impact of phones that can only be supported for three years or less. We provide security updates with bug fixes and other protections every month, and continually work with hardware and carrier partners to ensure that Android users have a fast, safe experience with their devices. When operating systems and security updates are delivered varies depending on the device, manufacturer and mobile operator.

Because smartphone makers will tweak bits of the Android operating system, they often deploy patches and updates at a slower pace than Google does on its own devices, or not at all. It's hurting Android security. Google's Pixel phones get Android version updates and security updates for at least three years from when the device first became available on the Google Store. While consumers are holding onto devices longer now, the average user will replace a handset after around three years.

Operating systems for other devices — like PCs — are supported for much longer. That's fantastic! Check out our comment policy here. Let's have a personal and meaningful conversation. Save my name, email, and website in this browser for the next time I comment.

Comments 1. The fun begins. Now, you need to start it in fastboot mode — to do this on the Nexus 6P, press and hold down the Volume Down and Power buttons on the handset from the off state. Once your device has booted in fastboot mode, open up the folder on your PC where you extracted the Android O image to. Click into the folder until you find a file called flash-all. Double click this to begin installing the new software onto your device.

Refer to the image above if you're confused at this point The next and final step: be patient! If all goes well, the process should take about five minutes. You can watch the process unfold in the command prompt menu.

Now, type the following commands. This will unlock your bootloader and wipe everything on your phone in the process. To re-lock the bootloader once Android Oreo is installed, simply enter the following command. So if your phone is stolen, the thief will be able to wipe it. These behavior changes apply exclusively to apps that are targeting Android 8.

Apps that compile against Android 8. Defining a valid ContentProvider with relevant permissions will help defend your app against content changes from malicious apps, and prevent you from leaking potentially private data to malicious apps.

Clickable View objects are now also focusable by default. If you want a View object to be clickable but not focusable, set the android:focusable attribute to false in the layout XML file containing the View , or pass in false to setFocusable in your app's UI logic.

Some pattern matches may cause browser-detection logic to misidentify a non-Opera browser as Opera. An example of such a pattern match might be:. To avoid issues arising from such a misidentification, use a string other than OPR as a pattern-match for the Opera browser.

To be granted access to an account, apps should either use , java. String[], java. String, java. String[], android. After getting access to accounts, an app can call AccountManager. Apps should instead use addOnAccountsUpdatedListener to get updates about accounts during runtime. Prior to Android 8. For apps targeting Android 8. The app is granted only the permissions it has explicitly requested. However, once the user grants a permission to the app, all subsequent requests for permissions in that permission group are automatically granted.

If the app targets Android 8. In apps targeting Android 8. Some apps might stop working because of this change if they have native libraries with incorrect load segments. This is a security-hardening measure. For more information, see Writable and Executable Segments. Linker changes are tied to the API level that an app targets. If there is a linker change at the targeted API level, the app cannot load the library.

The reverse was true in Android 7. Instead, if you want the default behavior in your List implementation, you should avoid overriding sort. For example:. For example, in versions of the platform prior to Android 8. This change makes the platform behavior more consistent: Either approach now results in a ConcurrentModificationException. The platform does not intercept direct calls from Java to the loadClass method, nor does it check the results of such calls. This behavior should not affect the functioning of well-behaved class loaders.

The platform checks that the descriptor of the class that the class loader returns matches the expected descriptor. If the returned descriptor does not match, the platform throws a NoClassDefFoundError error, and stores in the exception a detailed message noting the discrepancy. The platform also checks that the descriptors of the requested classes are valid. Doing so normally does not result in much memory overhead: If DEX files in the container are stored instead of compressed, the platform can perform an mmap operation on them rather than directly extracting them.

However, if the platform must extract the DEX file from the container, referencing a DEX file in this fashion may consume a lot of memory. In Android, all class loaders are considered parallel-capable. When multiple threads race to load the same class with the same class loader, the first thread to complete the operation wins, and the result is used for the other threads.

This behavior occurs regardless of whether the class loader has returned the same class, returned a different class, or thrown an exception. The platform silently ignores such exceptions. Caution: In versions of the platform lower than Android 8.

Changes for all apps These behavior changes apply to all apps when they run on the Android 8. Background execution limits As one of the changes that Android 8. Specifically: Apps that are running in the background now have limits on how freely they can access background services.

Apps cannot use their manifests to register for most implicit broadcasts that is, broadcasts that are not targeted specifically at the app. The new Context. The system allows apps to call Context.

However, the app must call that service's startForeground method within five seconds after the service is created.
