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_lines
adb 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 true
adb 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
