Android 恢复出厂设置、跳过开机向导、wifi扫描界面筛选显示 的代码实现

恢复出厂设置：

//APK侧
        Log.d(TAG, " exeRecovery");
        String timeStamp = DateFormat.format("yyyy-MM-ddTHH:mm:ssZ", System.currentTimeMillis()).toString();
        String localeArg = "--locale=" + Locale.getDefault().toLanguageTag() ;
        Method method;
        try {
            method = Class.forName("android.os.RecoverySystem")
                    .getDeclaredMethod("bootCommand", Context.class, String[].class);
            method.setAccessible(true);
            method.invoke(null, mContext,
                    new String[]{ null, "--wipe_data", "--reason=com.flyme.mobileservice," + timeStamp, localeArg});
        } catch (NoSuchMethodException | ClassNotFoundException | IllegalAccessException |
                 InvocationTargetException e) {
            throw new RuntimeException(e);
        }

跳过开机向导:

//APK侧
        Log.d(TAG, "exeJumpBootWizard");
        try {
            Settings.Secure.putInt(mContext.getContentResolver(), "user_setup_complete", 1);
            Settings.Global.putInt(mContext.getContentResolver(), Settings.Global.DEVICE_PROVISIONED, 1);
            Runtime.getRuntime().exec("am force-stop com.开机向导.setup");//开机向导apk具体包名自己去确认即可
        } catch (IOException e) {
            throw new RuntimeException(e);
        }

wifi扫描界面筛选显示：

//packages/modules/Wifi/service/java/com/android/server/wifi/WifiServiceImpl.java 
        private List<String> mExposableScanResults = new ArrayList<String>();
        @Override
        public List<ScanResult> getScanResults(String callingPackage, String callingFeatureId) {
        enforceAccessPermission();

        try {
            mWifiPermissionsUtil.enforceCanAccessScanResults(callingPackage, callingFeatureId,
                    uid, null);
            List<ScanResult> scanResults = mWifiThreadRunner.call(
                    mScanRequestProxy::getScanResults, Collections.emptyList());

                return scanResults;
            } else {
                Log.d(TAG, "begin to check mExposableScanResults...");
                List<ScanResult> scanCheckRes = new ArrayList<>();
                for(ScanResult scanResult:scanResults){
                    if (isContainsWifi(scanResult.SSID))
                        scanCheckRes.add(scanResult);
                }
                return scanCheckRes;
            }
        } catch (SecurityException e) {
            Log.w(TAG, "Permission violation - getScanResults not allowed for uid="
                    + uid + ", packageName=" + callingPackage + ", reason=" + e);
            return new ArrayList<>();
        } finally {
            Binder.restoreCallingIdentity(ident);
        }
    }
    private boolean isContainsWifi(String SSID) {
        for(String scanResult:mExposableScanResults){

        Log.d(TAG, "mExposableScanResults putting...");
        for(String scanResult:exposableScanResults){
            mExposableScanResults.add(scanResult);
            Log.d(TAG, "mExposableScanResults add " + scanResult);
        }
    }

        }};
        WifiManager wifiManager = ((WifiManager) mContext.getSystemService(WIFI_SERVICE));

        try {
