1.屏蔽Settings里面的连续五次点击版本号打开开发者模式功能
开发者模式是在Settings里面
找到对应目录：alps/packages/app/Settings/src/com/android/settings/deviceinfo
对应的Java文件：BuildNumberPreferenceController.java
对应的方法：handlePreferenceTreeClick()
@Overridepublic boolean handlePreferenceTreeClick(Preference preference) {if (!TextUtils.equals(preference.getKey(), getPreferenceKey())) {return false;}if (Utils.isMonkeyRunning()) {return false;}// Don't enable developer options for secondary non-demo users.if (!(mUm.isAdminUser() || mUm.isDemoUser())) {mMetricsFeatureProvider.action(mContext, SettingsEnums.ACTION_SETTINGS_BUILD_NUMBER_PREF);return false;}// Don't enable developer options until device has been provisionedif (!Utils.isDeviceProvisioned(mContext)) {mMetricsFeatureProvider.action(mContext, SettingsEnums.ACTION_SETTINGS_BUILD_NUMBER_PREF);return false;}if (mUm.hasUserRestriction(UserManager.DISALLOW_DEBUGGING_FEATURES)) {if (mUm.isDemoUser()) {// Route to demo device owner to lift the debugging restriction.final ComponentName componentName = Utils.getDeviceOwnerComponent(mContext);if (componentName != null) {final Intent requestDebugFeatures = new Intent().setPackage(componentName.getPackageName()).setAction("com.android.settings.action.REQUEST_DEBUG_FEATURES");final ResolveInfo resolveInfo = mContext.getPackageManager().resolveActivity(requestDebugFeatures, 0);if (resolveInfo != null) {mContext.startActivity(requestDebugFeatures);return false;}}}if (mDebuggingFeaturesDisallowedAdmin != null &&!mDebuggingFeaturesDisallowedBySystem) {RestrictedLockUtils.sendShowAdminSupportDetailsIntent(mContext,mDebuggingFeaturesDisallowedAdmin);}mMetricsFeatureProvider.action(mContext, SettingsEnums.ACTION_SETTINGS_BUILD_NUMBER_PREF);return false;}if (mDevHitCountdown > 0) {mDevHitCountdown--;if (mDevHitCountdown == 0 && !mProcessingLastDevHit) {// Add 1 count back, then start password confirmation flow.mDevHitCountdown++;final ChooseLockSettingsHelper helper =new ChooseLockSettingsHelper(mActivity, mFragment);mProcessingLastDevHit = helper.launchConfirmationActivity(REQUEST_CONFIRM_PASSWORD_FOR_DEV_PREF,mContext.getString(R.string.unlock_set_unlock_launch_picker_title));//这个就是连续点击五次之后打开开发者模式的函数，注释掉//enableDevelopmentSettings();mMetricsFeatureProvider.action(mMetricsFeatureProvider.getAttribution(mActivity),MetricsEvent.FIELD_SETTINGS_BUILD_NUMBER_DEVELOPER_MODE_ENABLED,mFragment.getMetricsCategory(),null,mProcessingLastDevHit ? 0 : 1);} else if (mDevHitCountdown > 0&& mDevHitCountdown < (TAPS_TO_BE_A_DEVELOPER - 2)) {if (mDevHitToast != null) {mDevHitToast.cancel();}mDevHitToast = Toast.makeText(mContext,mContext.getResources().getQuantityString(R.plurals.show_dev_countdown, mDevHitCountdown,mDevHitCountdown),Toast.LENGTH_SHORT);//这个是当你点击版本号的时，会弹出来toast提示还要点击多少次，这个也注释掉//mDevHitToast.show();}mMetricsFeatureProvider.action(mMetricsFeatureProvider.getAttribution(mActivity),MetricsEvent.FIELD_SETTINGS_BUILD_NUMBER_DEVELOPER_MODE_ENABLED,mFragment.getMetricsCategory(),null,0);} else if (mDevHitCountdown < 0) {if (mDevHitToast != null) {mDevHitToast.cancel();}mDevHitToast = Toast.makeText(mContext, R.string.show_dev_already,Toast.LENGTH_LONG);mDevHitToast.show();mMetricsFeatureProvider.action(mMetricsFeatureProvider.getAttribution(mActivity),MetricsEvent.FIELD_SETTINGS_BUILD_NUMBER_DEVELOPER_MODE_ENABLED,mFragment.getMetricsCategory(),null,1);}return true;}/*** Enables development settings. Only call this after confirming password.*/private void enableDevelopmentSettings() {mDevHitCountdown = 0;mProcessingLastDevHit = false;DevelopmentSettingsEnabler.setDevelopmentSettingsEnabled(mContext, true);//最终打开开发者模式的地方if (mDevHitToast != null) {mDevHitToast.cancel();}mDevHitToast = Toast.makeText(mContext, R.string.show_dev_on,Toast.LENGTH_LONG);mDevHitToast.show();}注释掉对应的code之后，就成功屏蔽了点击版本号打开开发者模式的功能了
2.通过计算器暗码来打开开发者模式
2.1添加暗码：
路径：packages/apps/ExactCalculator/src/com/android/calculator2/Calculator.java
网上有很多计算器添加暗码的案例，这里就不细说了，贴上代码：
@@ -999,6 +1000,25 @@ public class Calculator extends ActivitymEvaluator.requireResult(Evaluator.MAIN_INDEX, this, mResultText);}}
+ if (mFormulaText.getText().toString().equals("%147%+")) {
+ Log.i("xyx", "input %147%+ ==============>");
+ Intent intent = new Intent();
+ intent.setAction("action.wiwood.enable_Development_Settings");
+ sendBroadcast(intent);
+ Log.i("xyx", "start intent com.boll.factorymodetest ==============>");
+ }
+ //end}private void onDelete() {
这里是通过发送广播的方式来打开开发者模式；
2.2添加广播接收器
路径：alps/packages/app/Settings/src/com/android/settings/deviceinfo
这里用的是静态广播的办法，在这里新建一个DevelopmentEnabledReceiver.java

import android.content.Context;
import android.content.Intent;
import android.util.Log;import com.android.settingslib.development.DevelopmentSettingsEnabler;public class DevelopmentEnabledReceiver extends BroadcastReceiver {private final String TAG = "DevelopmentEnabledReceiver";@Overridepublic void onReceive(Context context, Intent intent) {Log.i(TAG, "Receive BroadCast:-----------------> action.wiwood.enable_Development_Settings");DevelopmentSettingsEnabler.setDevelopmentSettingsEnabled(context, true);}
}添加了广播接收器之后还要在AndroidManifest.xml里面声明一下：
--- a/mediatek/proprietary/packages/apps/MtkSettings/AndroidManifest.xml
+++ b/mediatek/proprietary/packages/apps/MtkSettings/AndroidManifest.xml
@@ -1918,6 +1918,16 @@<receiver android:name=".deviceinfo.StorageUnmountReceiver"android:exported="true"android:permission="android.permission.MOUNT_UNMOUNT_FILESYSTEMS" />

+ <receiver android:name=".deviceinfo.DevelopmentEnabledReceiver"
+ android:enabled="true"
+ android:exported="true">
+ <intent-filter>
+ <action android:name="action.wiwood.enable_Development_Settings"/>
+ </intent-filter>
+ </receiver>
+ <!-- end xyx -->
至此，就完成了所有代码的修改，编译Settings.apk和Calculator.apk，push到机器对应的路径下验证就ok了
