It means a benign program is wrongfully flagged as malicious due to an overly broad detection signature or algorithm used in an antivirus program.
What do you think about Android Studio? Do you recommend it? Android Studio for Windows. Softonic review. Cathy Buggs Updated 10 months ago. Android Studio for PC. You can export a Settings. The idea. To create a new idea. The following idea.
For a complete list of properties, read about the idea. If you are running Android Studio on a machine with less than the recommended specifications see System Requirements , you can customize the IDE to improve performance on your machine, as follows:.
Disable unnecessary lint checks: To change which lint checks Android Studio runs on your code, do the following:. Debug on a physical device: Debugging on an emulator uses more memory than debugging on a physical device, so you can improve overall performance for Android Studio by debugging on a physical device. Include only necessary Google Play services as dependencies: Including Google Play Services as dependencies in your project increases the amount of memory necessary.
Only include necessary dependencies to improve memory usage and performance. Reduce the maximum heap size available for Gradle: Gradle's default maximium heap size is 1, MB. Reduce the value by overriding the org. Do not enable parallel compilation: Android Studio can compile independent modules in parallel, but if you have a low-memory system you should not turn on this feature. To check this setting, do the following:. To use the bundled JDK, do the following:. By default, the Java language version used to compile your project is based on your project's compileSdkVersion because different versions of Android support different versions of Java.
If necessary, you can override this default Java version by adding the following compileOptions block to your build. For more information about where compileSdkVersion is defined, read about the module-level build file. Proxies serve as intermediary connection points between HTTP clients and web servers that add security and privacy to internet connections.
When running the Android plugin for Gradle from the command line or on machines where Android Studio is not installed, such as continuous integration servers, set the proxy settings in the Gradle build file.

Watch the following video for an overview of some emulator features. Requirements and recommendations The Android Emulator has additional requirements beyond the basic system requirements for Android Studio , which are described below: SDK Tools Android virtual devices Each instance of the Android Emulator uses an Android virtual device AVD to specify the Android version and hardware characteristics of the simulated device.
Run an app on the Android Emulator You can run an app from an Android Studio project, or you can run an app that's been installed on the Android Emulator as you would run any app on a device. Double-click an AVD, or click Run. The Android Emulator loads. Run the Android Emulator directly in Android Studio Run the Android Emulator directly in Android Studio to conserve screen real estate, to navigate quickly between the emulator and the editor window using hotkeys, and to organize your IDE and emulator workflow in a single application window.
Start your virtual device using the AVD Manager or by targeting it when running your app. Limitations Currently, you can't use the emulator's extended controls when it's running in a tool window. Snapshots A snapshot is a stored image of an AVD Android Virtual Device that preserves the entire state of the device at the time that it was saved — including OS settings, application state, and user data.
Save Quick Boot snapshots When you close an AVD, you can specify whether the emulator automatically saves a snapshot when you close.
To control this behavior, proceed as follows: Open the emulator's Extended controls window. In the Snapshots category of controls, navigate to the Settings tab.
Use the Auto-save current state to Quickboot drop-down menu to select one of the following options: Yes : Always save an AVD snapshot when you close the emulator. No : Don't save an AVD snapshot when you close the emulator. Delete a snapshot To manually delete a snapshot, open the emulator's Extended controls window, select the Snapshots category, select the snapshot, and click the delete button at the bottom of the window.
Load a snapshot To load a snapshot at any time, open the emulator's Extended controls window, select the Snapshots category, choose a snapshot, and click the load button at the bottom of the window. Select Cold boot. Snapshot requirements and troubleshooting Snapshots do not work with Android 4. Snapshots do not work with ARM system images for Android 8. Snapshots are not reliable when software rendering is enabled.
Loading or saving a snapshot is a memory-intensive operation. If you do not have enough RAM free when a load or save operation begins, the operating system may swap the contents of RAM to the hard disk, which can greatly slow the operation. If you experience very slow snapshot loads or saves, you may be able to speed these operations by freeing RAM. Closing applications that are not essential for your work is a good way to free RAM. Navigate the emulator screen Use your computer mouse pointer to mimic your finger on the touchscreen; select menu items and input fields; and click buttons and controls.
Table 1. Gestures for navigating the emulator Feature Description Swipe the screen Point to the screen, press and hold the primary mouse button, swipe across the screen, and then release. Drag an item Point to an item on the screen, press and hold the primary mouse button, move the item, and then release. Tap touch. Pressing Control Command on Mac brings up a pinch gesture multi-touch interface.
The mouse acts as the first finger, and across the anchor point is the second finger. Drag the cursor to move the first point. Clicking the left mouse button acts like touching down both points, and releasing acts like picking both up. Point to the screen, press and hold the primary mouse button, swipe across the screen, and then release. Point to an item on the screen, press and hold the primary mouse button, move the item, and then release. Point to the screen, press the primary mouse button, and then release.
For example, you could click a text field to start typing in it, select an app, or press a button. Point to an item on the screen, press the primary mouse button, hold, and then release.
For example, you could open options for an item. You can type in the emulator by using your computer keyboard, or using a keyboard that pops up on the emulator screen. For example, you could type in a text field after you selected it.
Open a vertical menu on the screen and use the scroll wheel mouse wheel to scroll through the menu items until you see the one you want. Click the menu item to select it. Resize the emulator as you would any other operating system window.
