清楚应用数据和卸载应用，直接执行命令：
* String cmd = "pm clear " + packageName; 或者 * String cmd = "pm clear " + packageName + " HERE";
* String cmd = "pm uninstall " + packageName; 或者 * String cmd = "pm uninstall " + packageName + " HERE";
* String cmd = "pm install " + apk_path; 或者 * String cmd = "pm uninstall " + apk_path+ " HERE";
且在清楚数据之后应用本身的Service和Alarm定时会自动取消掉，进程也随之结束， 以此类推adb所有命令都可以这样执行。
package com.app.exit.demo;
import java.io.IOException;
import android.util.Log;
/**
* 运行命令管理器
* 等同于在PC端adb shell之后执行命令，pm clear packageName
* 但是只能回自己操作，不能清除其他应用的数据；
* 卸载其他应用(限root设备或者厂商提供接口)

public class RuntimeCmdManager {
private static final String TAG = "RuntimeCmdManager";
/**
* 清除应用缓存的用户数据，同时停止所有服务和Alarm定时task
* String cmd = "pm clear " + packageName;
* String cmd = "pm clear " + packageName + " HERE";

* @return
*/

if (p == null) {
LogTag.log("Clear app data packageName:" + packageName

} else {

}
return p;
}
/**

* String cmd = "pm uninstall " + packageName;
* Runtime.getRuntime().exec("pm uninstall " + packageName)

*/
public static Process uninstallApp(String packageName) {
Process p = execRuntimeProcess("pm uninstall " + packageName);
if (p == null) {
LogTag.log("Uninstall app packageName:" + packageName + ", FAILED !");
} else {
LogTag.log("Uninstall app packageName:" + packageName + ", SUCCESS !");
}
return p;
}
public static Process execRuntimeProcess(String commond) {
Process p = null;
try {
p = Runtime.getRuntime().exec(commond);
} catch (IOException e) {
LogTag.log("exec Runtime commond:" + commond + ", IOException" + e);
e.printStackTrace();
}
LogTag.log("exec Runtime commond:" + commond + ", Process:" + p);
return p;
}
}
彻底退出应用，不清除数据的方法：
停止应用中所有Service。调用ActivityManager.killBackgroundProcesses(packageName);
