App性能调试详解

Android App性能监控工具

更多系统属性参考

一、开启 GPU Render 的profiling bar： Gpu渲染速度

adb shell setprop debug.hwui.profile true
adb shell setprop debug.hwui.profile visual_bars 
adb shell setprop debug.hwui.profile visual_linesadb shell setprop debug.hwui.profile false#控制汇总条长度
adb shell setprop debug.hwui.profile.maxframes 400 

效果如下：

其中， Android 6.0 及更高版本的设备时分析器输出中某个竖条的每个区段如下所示：

下表显示的是 Android 4.0 和 5.0 中的竖条区段。

系统源码 ：

/*** System property used to enable or disable hardware rendering profiling.* The default value of this property is assumed to be false.* When profiling is enabled, the adb shell dumpsys gfxinfo command will* output extra information about the time taken to execute by the last* frames.* Possible values:* "true",        to enable profiling* "visual_bars", to enable profiling and visualize the results on screen* "false",       to disable profiling* @see #PROFILE_PROPERTY_VISUALIZE_BARS* @hide*/
public static final String PROFILE_PROPERTY = "debug.hwui.profile";

/*** System property used to specify the number of frames to be used* when doing hardware rendering profiling.* The default value of this property is #PROFILE_MAX_FRAMES.** When profiling is enabled, the adb shell dumpsys gfxinfo command will* output extra information about the time taken to execute by the last* frames.** Possible values:* "60", to set the limit of frames to 60*/
static final String PROFILE_MAXFRAMES_PROPERTY = "debug.hwui.profile.maxframes";

二、打开 Overdraw 检查 : GPU过度绘制

adb shell setprop debug.hwui.overdraw show# adb shell setprop debug.hwui.overdraw false

系统源码：

/** Controls overdraw debugging.** Possible values:* "false", to disable overdraw debugging* "show",  to show overdraw areas on screen* "count", to display an overdraw counter** @hide*/
public static final String DEBUG_OVERDRAW_PROPERTY = "debug.hwui.overdraw";

三、开启显示各个view的布局线 : 布局边界

adb shell setprop debug.layout true# adb shell setprop debug.layout false

系统源码 ：

/*** When set to true, apps will draw debugging information about their layouts.** @hide*/
public static final String DEBUG_LAYOUT_PROPERTY = "debug.layout";

参考

四、查看dirty区域：

adb shell setprop debug.hwui.show_dirty_regions trueadb shell setprop debug.hwui.render_dirty_regions true

系统源码：

/**
* System property used to enable or disable dirty regions invalidation.
* This property is only queried if {@link #RENDER_DIRTY_REGIONS} is true.
* The default value of this property is assumed to be true.
*
* Possible values:
* "true",  to enable partial invalidates
* "false", to disable partial invalidates
*/
static final String RENDER_DIRTY_REGIONS_PROPERTY = "debug.hwui.render_dirty_regions";/**
* Turn on to draw dirty regions every other frame.
*
* Possible values:
* "true",  to enable dirty regions debugging
* "false", to disable dirty regions debugging
*
* @hide
*/
public static final String DEBUG_DIRTY_REGIONS_PROPERTY = "debug.hwui.show_dirty_regions";

五、log日志

# 使能所有log tag 输出，设置所有log V等级及以上的log才能输出
adb shell setprop persist.log.tag V
