分享自己第一次修改6.0源碼并編譯成功的經歷——修改恢復出廠設置原生dialog

前言廢話

一直以來都是從事應用層的開發,也沒有什么機會接觸到怎么修改系統層源碼怎么編譯整個系統,直到現在在的公司,是從事手機研發和智能后視鏡的研發才有這個機會和親眼目睹一整套從修改底源碼定制root到編譯系統出來再到應用層的開發是怎么工作起來的,因為自己也蠢蠢欲動開始初次嘗試這些工作,有點小激動...........,廢話不說了開始,過程很痛苦.....

未修改前這個原生是長什么樣子的
需求需要修改的樣子
思路
  • 在應用層先實現這個dialog的效果
  • 找到恢復出廠設置所在的源碼位置,把我們實現好的dialog替換原生的dialog
在應用層實現,這里只粘貼部分代碼

CustomWaitDialog的簡單使用
new CustomWaitDialog.Builder(this).setText("正在恢復出廠設置").build().show();
效果
在應用層實現很簡單,也能實現預期的效果,接下來查看源碼恢復出廠設置的代碼所在的位置,在這里我所修改的是MTK提供的android 6.0源碼,其他的改動位置估計也差不多,但要實踐才知道。
  • 找到位置\alps\frameworks\base\services\core\java\com\android\server\power目錄下的ShutdownThread.java文件

  • 分析這個類的源碼。這里順便說 ,我還不知道有什么比較好的ide查看源碼,所以我是用vim打開的。
    1、查看beginShutdownSequence()代碼

    
         .....
         ......
        // Throw up a system dialog to indicate the device is rebooting / shutting down.
        ProgressDialog pd = new ProgressDialog(context);
    
        // Path 1: Reboot to recovery and install the update
        //   Condition: mRebootReason == REBOOT_RECOVERY and mRebootUpdate == True
        //   (mRebootUpdate is set by checking if /cache/recovery/uncrypt_file exists.)
        //   UI: progress bar
        //
        // Path 2: Reboot to recovery for factory reset
        //   Condition: mRebootReason == REBOOT_RECOVERY
        //   UI: spinning circle only (no progress bar)
        //
        // Path 3: Regular reboot / shutdown
        //   Condition: Otherwise
        //   UI: spinning circle only (no progress bar)
        if (PowerManager.REBOOT_RECOVERY.equals(mRebootReason)) {
            mRebootUpdate = new File(UNCRYPT_PACKAGE_FILE).exists();
            if (mRebootUpdate) {
                pd.setTitle(context.getText(com.android.internal.R.string.reboot_to_update_title));
                pd.setMessage(context.getText(
                        com.android.internal.R.string.reboot_to_update_prepare));
                pd.setMax(100);
                pd.setProgressNumberFormat(null);
                pd.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);
                pd.setProgress(0);
                pd.setIndeterminate(false);
            } else {
                // Factory reset path. Set the dialog message accordingly.
                pd.setTitle(context.getText(com.android.internal.R.string.reboot_to_reset_title));
                pd.setMessage(context.getText(
                        com.android.internal.R.string.reboot_to_reset_message));
                pd.setIndeterminate(true);
            }
        } else {
            pd.setTitle(context.getText(com.android.internal.R.string.power_off));
            pd.setMessage(context.getText(com.android.internal.R.string.shutdown_progress));
            pd.setIndeterminate(true);
        }
        pd.setCancelable(false);
        pd.getWindow().setType(WindowManager.LayoutParams.TYPE_KEYGUARD_DIALOG);
    
        // start the thread that initiates shutdown
        sInstance.mContext = context;
        sInstance.mPowerManager = (PowerManager)context.getSystemService(Context.POWER_SERVICE);
        sInstance.mHandler = new Handler() {
        };
    
        beginAnimationTime = 0;
        boolean mShutOffAnimation = configShutdownAnimation(context);
        int screenTurnOffTime = getScreenTurnOffTime(context);
        synchronized (mEnableAnimatingSync) {
            if (mEnableAnimating) {
                if (mShutOffAnimation) {
                    Log.d(TAG, "mIBootAnim.isCustBootAnim() is true");
                    bootanimCust(context);
                } else {
                    pd.show();
    
                    sInstance.mProgressDialog = pd;
                }
                sInstance.mHandler.postDelayed(mDelayDim, screenTurnOffTime);
            }
        }
    
 分析:ProgressDialog  是系統的dialog,然后稍微往下看到.show()方法才是重點,這里說明了什么時候show出來,show出來之后又把這個dialog賦給了sInstance.mProgressDialog,接下來就要找這個sInstance.mProgressDialog,在什么時候給dismiss掉。

 2、查看running()代碼
```java
......
......
            //To void previous UI flick caused by shutdown animation stopping before BKL turning off
            if (sInstance.mProgressDialog != null) {
                sInstance.mProgressDialog.dismiss();
            } else if (beginAnimationTime > 0) {
                Log.i(TAG, "service.bootanim.exit = 1");
                SystemProperties.set("service.bootanim.exit", "1");
            }
.......
.......

分析:順利找到dismiss的位置。接下來就是修改這兩個位置

開始修改ShutdownThread.java 這個類的源碼
  • 申明全局變量CustomWaitDialog
        // IPO
      private static CustomWaitDialog pd = null;
    
  • 修改 beginShutdownSequence()方法

        sInstance.mHandler = new Handler() {
        };

        beginAnimationTime = 0;
        boolean mShutOffAnimation = configShutdownAnimation(context);
        int screenTurnOffTime = getScreenTurnOffTime(context);
        synchronized (mEnableAnimatingSync) {
            if (mEnableAnimating) {
                if (mShutOffAnimation) {
                    Log.d(TAG, "mIBootAnim.isCustBootAnim() is true");
                    bootanimCust(context);
                } else {
                     pd = new CustomWaitDialog.Builder(context).build();
                    //luhaisheng 2016/10/10
                    if(mReboot){
                        pd.setText(context.getText(com.android.internal.R.string.custom_text_reboot_ing));
                    }else{
                        pd.setText(context.getText(com.android.internal.R.string.custom_text_off_ing));
                        }
                    pd.getWindow().setType(WindowManager.LayoutParams.TYPE_KEYGUARD_DIALOG);
                    /* To fix video+UI+blur flick issue */
                    pd.getWindow().addFlags(WindowManager.LayoutParams.FLAG_DIM_BEHIND);
                    pd.show();
            
       //luhaisheng 2016/10/10
                  //  pd.show();

                  //  sInstance.mProgressDialog = pd;
                }
                sInstance.mHandler.postDelayed(mDelayDim, screenTurnOffTime);
            }
        }

在這里主要修改三個地方,第一個是注釋掉原來pd的地方,第二個是在

if(mReboot){ 
pd.setText(context.getText(com.android.internal.R.string.custom_text_reboot_ing)); 
}else{ 
pd.setText(context.getText(com.android.internal.R.string.custom_text_off_ing)); }

通過mReboot判斷是否重啟,第三個是注釋掉原來的show方法。

  • 修改 running()
            //To void previous UI flick caused by shutdown animation stopping before BKL turning off
          //  if (sInstance.mProgressDialog != null) {
           //     sInstance.mProgressDialog.dismiss();
            //2016-09-24 luhaisheng
             if(pd!=null){
                 pd.dismiss();
                 pd=null;
            } else if (beginAnimationTime > 0) {
                Log.i(TAG, "service.bootanim.exit = 1");
                SystemProperties.set("service.bootanim.exit", "1");
            }

在原來的判斷dimiss方法上修改。以上就是修改ShutdownThread.java所做的工作,看起來也不簡單,因為要分析源碼,而且不能像修改應用層那么便捷因為你還沒有引用資源,自定義的類,還要編譯系統,刷機才能看到最終的效果,反正繼續往下做,至于為什么這么修改,有時間的同學自己研究下源碼,看這么修改是否有問題,也可以有其他的修改方式。

引入自定義類 CircularProgressView和CustomWaitDialog

*在alps\frameworks\base\services\core\java\com\android\server\power目錄下放置
CircularProgressView.java與CustomWaitDialog.java,也就是與修改的ShutdownThread.java同級。

*編輯CircularProgressView.java 修改導入的包名和引入的R。修改如下

package com.android.server.power;

import android.animation.Animator;
import android.animation.ObjectAnimator;
import android.animation.ValueAnimator;
import android.content.Context;
import android.content.res.TypedArray;
import android.graphics.Canvas;
import android.graphics.Color;
import android.graphics.Paint;
import android.graphics.Paint.Cap;
import android.graphics.RectF;
import android.util.AttributeSet;
import android.util.Property;
import android.view.View;
import android.view.animation.AccelerateDecelerateInterpolator;
import android.view.animation.Interpolator;
import android.view.animation.LinearInterpolator;

import com.android.internal.R;
.....

分析:就修改了兩個地方,package 是com.android.server.power,和導入的R是com.android.internal.R,不然肯定出錯。
同理CustomWaitDialog.java 也是這么改的。

添加資源文件和修改資源文件(最最最麻煩的地方)
  • 在alps\frameworks\base\core\res\res\drawable-hdpi目錄下放置資源圖片,我這里只需要放置一張
  • 為添加的資源圖片文件添加id(id 是自己手動添加的 沒有ide 自動導入 很麻煩),編輯alps\frameworks\base\core\res\res\values 目錄下public.xml的文件,自增一個type="drawable" 的item。我的是
<public type="drawable" name="laun_po_bg"  id="0x010800b6"/>
  • 為布局文件中的控件TextView申明id text_off_or_reboot。編譯alps\frameworks\base\core\res\res\目錄下ids.xml的文件,編輯如下:
<!--2016 1009 luhaisheng-->
  <item type="id" name="text_off_or_reboot" />

  <item type="id" name="pv" />

所以你自己定義的控件id都需要再ids.xml下做申明,還需要在public.xml下添加id,添加如下:

      <public type="id" name="text_off_or_reboot" id="0x0102003e"/>
      <public type="id" name="pv" id="0x0102003f"/>
  • 與添加控件的id類似,所以自定義的style,layout,string,color等,都需要在相應的目錄下申明,然后在public.xml下添加id。我的public.xml如下所示:

      <public type="style" name="CustomDialogHolo" id="0x010302e0"/>
      <public type="layout" name="custom_wait_dialog_layout" id="0x01090018"/>
      <public type="id" name="text_off_or_reboot" id="0x0102003e"/>
      <public type="id" name="pv" id="0x0102003f"/>

      <public type="string" name="custom_text_off_ing" id="0x01040019"/>
      <public type="string" name="custom_text_reboot_ing" id="0x01040020"/>
      <public type="drawable" name="laun_po_bg"  id="0x010800b6"/>
     
      <public type="attr" name="borderWidth" id="0x010104f2" />
       <public type="attr" name="colorSequence" id="0x010104f3" />
       <public type="attr" name="sweepAnimationDurationMillis" id="0x010104f4" />
       <public type="attr" name="angleAnimationDurationMillis" id="0x010104f5" />
        <public type="attr" name="minSweepAngle" id="0x010104f6" />

      <public type="array" name="circular_default_color_sequence" id="0x01070006" />
      
       <public type="color" name="circular_blue" id="0x0106001c" />
等資源添加確定無誤后,其實誰也不能確定,那么就開執行編譯吧,因為出錯看錯就好了,像這種一般都是添加資源時候漏了申明某個id,或者id沖突之類的,我就錯了好幾十次了,保存好所有修改,后在framework/base/core/res/res/ 下mm編譯一次,無誤后在跟目錄下make update-api,update成功之后就可以編譯整個系統了。
  • 在跟目錄下執行 source build/envsetup.sh
  • lunch 找到與你硬件相對于的版本
  • make -j8 開始編譯整個系統
這個過程下來從update到編譯這個系統我的計算機花了差不多兩個小時,從中還有不少的錯誤,一直到正確出來刷機花了一天的時間,所以搞這方面的真的很需要耐心。至于系統怎么編譯,這個不是我說所的重點。不懂的請自己google。接下來我傳上,我修改源碼的所以涉及到的文件和資源到github。https://github.com/justinhaisheng/-----Mask_Clear
