上一讲 讲了如何创建一个user
为什么要创建User 例如window 系统创建了一个user 会在当前用户下进行操作,而android 多用户体系就像window系统
创建了一个user之后在当前user下进行操作,就可以再安装或者启动一个应用。
有了一个user 之后在这个user下创建一个工作空间,在工作空间下安装 启动apk 就可以双开了。
具体类操作:
package android.app.admin; import android.content.ComponentName; import android.content.Intent; import android.content.IntentFilter; import android.net.ProxyInfo; import android.os.Bundle; import android.os.PersistableBundle; import android.os.RemoteCallback; import android.os.UserHandle; import java.util.List; /** * Internal IPC interface to the device policy service. * {@hide} */ interface IDevicePolicyManager { void setPasswordQuality(in ComponentName who, int quality, int userHandle);
