开机自启动（小米需要在安全中心设置自启动）

//在广播中声明
  String action = intent.getAction();
      if (action.equals("android.intent.action.BOOT_COMPLETED")) {
            Intent activity = new Intent(context, SecondActivity.class);
            activity.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
            context.startActivity(activity);
     } 
  <receiver android:name=".xxx.xxx">

静默安装（需要root）

    public static boolean installUseRoot(String filePath) {
        if (TextUtils.isEmpty(filePath))
            throw new IllegalArgumentException("Please check apk file path!");
        boolean result = false;
        Process process = null;
        OutputStream outputStream = null;
        BufferedReader errorStream = null;
        try {
            process = Runtime.getRuntime().exec("su");
            outputStream = process.getOutputStream();
            String command = "pm install -r " + filePath + "\n";
            outputStream.write(command.getBytes());
            outputStream.flush();
            outputStream.write("exit\n".getBytes());
            outputStream.flush();
            process.waitFor();
            errorStream = new BufferedReader(new InputStreamReader(process.getErrorStream()));
            StringBuilder msg = new StringBuilder();
            String line;
            while ((line = errorStream.readLine()) != null) {
                msg.append(line);
            }
            Log.d(TAG, "install msg is " + msg);
            if (!msg.toString().contains("Failure")) {
                result = true;
            }
        } catch (Exception e) {
            Log.e(TAG, e.getMessage(), e);
        } finally {
            try {
                if (outputStream != null) {
                    outputStream.close();
                }
                if (errorStream != null) {
                    errorStream.close();
                }
            } catch (IOException e) {
                outputStream = null;
                errorStream = null;
                process.destroy();
            }
        }
        return result;
    }

关机代码块（root）

    public static void closeOs(Context context) {
        try {
            Process proc = Runtime.getRuntime().exec(new String[]{"su", "-c", "reboot -p"});  //关机
        } catch (IOException e) {
            e.printStackTrace();
        }
    }

非Root的智能安装（可以）

原文链接：http://blog.csdn.net/fuchaosz/article/details/51852442

原理是用到了android提供的AccessibilityService服务，这个服务可以获取屏幕上的节点，一个节点也就是一个view，我们写的xml文件中每个标签就是一个节点，然后可以模拟用户的操作，对这些节点进行点击、滑动等操作。我们就是利用这个原理，来自动点击安装按钮的，当然使用这个服务必须用户手动开启无障碍服务。

创建AccessibilityService配置文件 在res目录下创建xml目录，然后在xml目录下创建一个accessibility_service_config.xml文件，内容如下 res/xml/accessibility_service_config.xml:

<accessibility-service xmlns:android="http://schemas.android.com/apk/res/android"
                       android:accessibilityEventTypes="typeAllMask"
                       android:accessibilityFeedbackType="feedbackGeneric"
                       android:accessibilityFlags="flagDefault"
                       android:canRetrieveWindowContent="true"
                       android:description="@string/desc"
                       android:packageNames="com.android.packageinstaller"
    />

• accessibilityEventTypes:指定我们在监听窗口中可以模拟哪些事件，typeAllMask表示所有的事件都能模拟.
• accessibilityFeedbackType:指定无障碍服务的反馈方式.
• canRetrieveWindowContent:指定是否允许我们的程序读取窗口中的节点和内容，当然是true.
• description: 当用户手动配置服务时，会显示给用户看.
• packageNames: 指定我们要监听哪个应用程序下的窗口活动，这里写com.android.packageinstaller表示监听Android系统的安装界面。 其余参数照写即可。 res/strings.xml:

创建AccessibilityService服务

public class MyAccessibilityService extends AccessibilityService {

    private static final String TAG = "[TAG]";
    private Map<Integer, Boolean> handleMap = new HashMap<>();

    @Override
    public void onAccessibilityEvent(AccessibilityEvent event) {
        AccessibilityNodeInfo nodeInfo = event.getSource();
        if (nodeInfo != null) {
            int eventType = event.getEventType();
            if (eventType == AccessibilityEvent.TYPE_WINDOW_CONTENT_CHANGED || eventType == AccessibilityEvent.TYPE_WINDOW_STATE_CHANGED) {
                if (handleMap.get(event.getWindowId()) == null) {
                    boolean handled = iterateNodesAndHandle(nodeInfo);
                    if (handled) {
                        handleMap.put(event.getWindowId(), true);
                    }
                }
            }

        }
    }

    @Override
    public void onInterrupt() {

    }

    //遍历节点，模拟点击安装按钮
    private boolean iterateNodesAndHandle(AccessibilityNodeInfo nodeInfo) {
        if (nodeInfo != null) {
            int childCount = nodeInfo.getChildCount();
            if ("android.widget.Button".equals(nodeInfo.getClassName())) {
                String nodeCotent = nodeInfo.getText().toString();
                Log.d(TAG, "content is: " + nodeCotent);
                if ("安装".equals(nodeCotent) || "完成".equals(nodeCotent) || "确定".equals(nodeCotent)) {
                    nodeInfo.performAction(AccessibilityNodeInfo.ACTION_CLICK);
                    return true;
                }
            }
            //遇到ScrollView的时候模拟滑动一下
            else if ("android.widget.ScrollView".equals(nodeInfo.getClassName())) {
                nodeInfo.performAction(AccessibilityNodeInfo.ACTION_SCROLL_FORWARD);
            }
            for (int i = 0; i < childCount; i++) {
                AccessibilityNodeInfo childNodeInfo = nodeInfo.getChild(i);
                if (iterateNodesAndHandle(childNodeInfo)) {
                    return true;
                }
            }
        }
        return false;
    }
}

AndroidManifest中配置服务

 <service
            android:name=".MyAccessibilityService"
            android:label="智能安装App"
            android:permission="android.permission.BIND_ACCESSIBILITY_SERVICE"
            >
            <intent-filter>
                <action android:name="android.accessibilityservice.AccessibilityService"/>
            </intent-filter>
            <meta-data
                android:name="android.accessibilityservice"
                android:resource="@xml/accessibility_service_config"
                />
        </service>

重点是后面的service标签:

• android:label：这个就是用户看到的无障碍服务的名称
• android:permission: 需要用到BIND_ACCESSIBILITY_SERVICE这个权限.
• action: android.accessibilityservice.AccessibilityService 有了这个action，用户才能在设置里面看到我们的服务，否则用户无法开启我们写的服务，也就不能进到我们写的MyAccessibilityService里面了.所以，注意不要写错了，如果你发现无障碍服务里面没有我们写的服务，请检查这里.

调用智能安装代码

   private void smartInstall() {
        Uri uri = Uri.fromFile(new File("/mnt/sdcard/test.apk"));
        Intent localIntent = new Intent(Intent.ACTION_VIEW);
        localIntent.setDataAndType(uri, "application/vnd.android.package-archive");
        startActivity(localIntent);
    }

手动配置智能安装服务

//跳转到开启智能安装服务的界面
Intent intent = new Intent(Settings.ACTION_ACCESSIBILITY_SETTINGS);
startActivity(intent);
