I am developing an application in which there is a button on click of that button i want the screenshot of android screen not that application screen my phone is unrooted. Is it possible to take screenshot of unrooted phone.?

推荐答案

是的，这是可能的.

查看 Android 屏幕截图库.

Android 屏幕截图库 (ASL) 能够以编程方式从 Android 设备捕获屏幕截图，而无需具有 root 访问权限.相反，ASL 使用在后台运行的本机服务，每次设备启动时通过 Android 调试桥 (ADB) 启动一次.

Android Screenshot Library (ASL) enables to programmatically capture screenshots from Android devices without requirement of having root access privileges. Instead, ASL utilizes a native service running in the background, started via the Android Debug Bridge (ADB) once per device boot.

如何实施?

修改清单 XML

为了可以访问 Android 服务，请将以下声明添加到您的客户端应用程序的 XML 清单中:

In order for Android service to be accessible, add the following declaration to your client application's XML manifest:

<service android:name="pl.polidea.asl.ScreenshotService">
    <intent-filter>
            <action android:name="pl.polidea.asl.ScreenshotService.BIND" />
            <category android:name="android.intent.category.DEFAULT"/>
    </intent-filter>
</service>

绑定服务

要获得 IScreenshotProvider 接口，必须使用 Context.bindService 绑定到 ASL 服务 (pl.polidea.asl.ScreenshotService) - 例如:

To obtain the IScreenshotProvider interface one must bind to the ASL service (pl.polidea.asl.ScreenshotService) using Context.bindService - for example:

// (using class name)
Intent intent = new Intent();
intent.setClass (this, pl.polidea.asl.ScreenshotService.class);
bindService (intent, aslServiceConnection, Context.BIND_AUTO_CREATE);
