安卓技術大講堂詳解添開屏特效教程

1、我們要實現特效的添加，首先需要做的是反編譯services.jar文件之后打開/com/android/server/PowerManagerService.smali文件找到getPreferredBrightness()I這行在上面添加：.method static synthetic getContextZZ(Lcom/android/server/PowerManagerService;)Landroid/content/Context; .registers 2 .parameter x0 .prologue iget-object v0, p0, Lcom/android/serv

2、er/PowerManagerService;-mContext:Landroid/content/Context; return-object v0.end method復制代碼打開/com/android/server/PowerManagerService$BrightnessState.smali文件找到# virtual methods這行在上面添加：.method private getScreenAnimationMode(Landroid/content/Context;)I .registers 7 .parameter context .prologue const v0,

3、 0 x0 const v3, 0 x1 const v4, 0 x10 invoke-virtual p1, Landroid/content/Context;-getContentResolver()Landroid/content/ContentResolver; move-result-object v1 const-string v2, config_beam_screen_on invoke-static v1, v2, v3, Landroid/provider/Settings$System;-getInt(Landroid/content/ContentResolver;Lj

4、ava/lang/String;I)I move-result v2 if-eqz v2, :cond_22 const v0, 0 x1 :goto_18 const-string v2, config_beam_screen_off invoke-static v1, v2, v3, Landroid/provider/Settings$System;-getInt(Landroid/content/ContentResolver;Ljava/lang/String;I)I move-result v2 if-eqz v2, :cond_21 add-int/2addr v0, v4 :c

5、ond_21 return v0 :cond_22 const v0, 0 x0 goto :goto_18.end method復制代碼繼續(xù)3中修改的文件找到.method public run()V從這一行刪除到下面第一個.end method那一行，也就是刪除run這個函數然后添加：.method public run()V .registers 10 .prologue const/4 v8, 0 x0 .line 2076 iget-object v4, p0, Lcom/android/server/PowerManagerService$BrightnessState;-this

6、$0:Lcom/android/server/PowerManagerService; invoke-static v4, Lcom/android/server/PowerManagerService;-getContextZZ(Lcom/android/server/PowerManagerService;)Landroid/content/Context; move-result-object v4 invoke-direct p0, v4, Lcom/android/server/PowerManagerService$BrightnessState;-getScreenAnimati
