因项目需要 需要用到 android 自带的命令 uiautomator dump

使用过程中发现 在android 5.0 以下版本中 uiautomator 遇到特殊字符，主要是emoji 表情，会出现错误，类似如下：

提示比较明显，根据提示直接查看 android 源代码就可以找到问题了，推荐在线查看代码的一个网站
http://androidxref.com/

这里android是4.2.2版本的，直接选择这个就可以

页面打开后，填入出错文件名，选择全部搜索，

找到后打开，找到对应出错行数102 和 105行

找到错误地方修改就容易了，只需要新增个方法过滤下特殊字符就行了，Java代码如下：

	public static String filterEmoji(String source) { 
        if(source != null)
        {
            String regEx="[\\p{P}\\p{Z}a-zA-Z0-9\\u4e00-\\u9fa5]";  
            Pattern p = Pattern.compile(regEx);     
            Matcher m = p.matcher(source);
            StringBuffer sb = new StringBuffer();
            while(m.find()){
            sb.append(m.group());
            }
        return sb.toString();
       }
       return source; 
    }

转换成smail代码如下：

.method public static filterEmoji(Ljava/lang/String;)Ljava/lang/String;
    .locals 5
    .param p0, "source"    # Ljava/lang/String;

    .prologue
    .line 24
    if-eqz p0, :cond_0

    .line 26
    const-string v2, "[\\pP\\pS\\pZa-zA-Z0-9\\u4e00-\\u9fa5]"

    .line 27
    .local v2, "regEx":Ljava/lang/String;
    invoke-static {v2}, Ljava/util/regex/Pattern;->compile(Ljava/lang/String;)Ljava/util/regex/Pattern;

    move-result-object v1

    .line 28
    .local v1, "p":Ljava/util/regex/Pattern;
    invoke-virtual {v1, p0}, Ljava/util/regex/Pattern;->matcher(Ljava/lang/CharSequence;)Ljava/util/regex/Matcher;

    move-result-object v0

    .line 29
    .local v0, "m":Ljava/util/regex/Matcher;
    new-instance v3, Ljava/lang/StringBuffer;

    invoke-direct {v3}, Ljava/lang/StringBuffer;-><init>()V

    .line 30
    .local v3, "sb":Ljava/lang/StringBuffer;
    :goto_0
    invoke-virtual {v0}, Ljava/util/regex/Matcher;->find()Z

    move-result v4

    if-nez v4, :cond_1

    .line 33
    invoke-virtual {v3}, Ljava/lang/StringBuffer;->toString()Ljava/lang/String;

    move-result-object p0

    .line 35
    .end local v0    # "m":Ljava/util/regex/Matcher;
    .end local v1    # "p":Ljava/util/regex/Pattern;
    .end local v2    # "regEx":Ljava/lang/String;
    .end local v3    # "sb":Ljava/lang/StringBuffer;
    .end local p0    # "source":Ljava/lang/String;
    :cond_0
    return-object p0

    .line 31
    .restart local v0    # "m":Ljava/util/regex/Matcher;
    .restart local v1    # "p":Ljava/util/regex/Pattern;
    .restart local v2    # "regEx":Ljava/lang/String;
    .restart local v3    # "sb":Ljava/lang/StringBuffer;
    .restart local p0    # "source":Ljava/lang/String;
    :cond_1
    invoke-virtual {v0}, Ljava/util/regex/Matcher;->group()Ljava/lang/String;

    move-result-object v4

    invoke-virtual {v3, v4}, Ljava/lang/StringBuffer;->append(Ljava/lang/String;)Ljava/lang/StringBuffer;

    goto :goto_0
.end method

这样只需要把手机里对应的uiautomator.odex 提取出来，把我们上面的smail代码添加上并且调用过滤，就可以了
首先提取 /system/framework/ 目录，是整个目录，一会要用到
打开adb shell

adb shell
$su
#mount -o remount,rw /system
#cp /system/framework /sdcard/framework
adb pull /sdcard/framework/ D:\odex\

导出后下载
baksmali-2.2.1.jar
smali-2.2.1.jar
这两个文件，和导出文件同一目录，并且电脑需要安装了jdk
然后命令行定位到导出framework的路径执行反编译命令

java -jar baksmali-2.2.1.jar deodex uiautomator.odex

执行完毕后会生成一个 out 的目录，里面存放的就是生成后的smail文件，查找目标文件，在路径
D:\odex\out\com\android\uiautomator\core\AccessibilityNodeInfoDumper.smali
关键代码片段如下：

.method private static dumpNodeRec(Landroid/view/accessibility/AccessibilityNodeInfo;Lorg/xmlpull/v1/XmlSerializer;I)V

    .line 134
    return-void
.end method

在文件尾部插入我们的方法smail代码

在

    invoke-virtual {p0}, Landroid/view/accessibility/AccessibilityNodeInfo;->getText()Ljava/lang/CharSequence;

    move-result-object v5

    invoke-static {v5}, Lcom/android/uiautomator/core/AccessibilityNodeInfoDumper;->safeCharSeqToString(Ljava/lang/CharSequence;)Ljava/lang/String;
	
    move-result-object v5

和

    invoke-virtual {p0}, Landroid/view/accessibility/AccessibilityNodeInfo;->getContentDescription()Ljava/lang/CharSequence;

    move-result-object v5

    invoke-static {v5}, Lcom/android/uiautomator/core/AccessibilityNodeInfoDumper;->safeCharSeqToString(Ljava/lang/CharSequence;)Ljava/lang/String;

    move-result-object v5

后面分别插入

	invoke-static {v5}, Lcom/android/uiautomator/core/AccessibilityNodeInfoDumper;->filterEmoji(Ljava/lang/String;)Ljava/lang/String;
	
	move-result-object v5

来调用我们的方法

invoke-static {v5}, Lcom/android/uiautomator/core/AccessibilityNodeInfoDumper;->filterEmoji(Ljava/lang/String;)Ljava/lang/String;

上面这句话可以理解为静态方法调用{v5}是参数

move-result-object v5

这句是调用结果给 v5

改好之后，执行

java -jar smali-2.2.1.jar assemble out

目录下会生成一个 out.dex ，修改成classes.dex
然后用解压缩软件打开 uiautomator.jar 把 它放进去 然后放回到 /system/framework/ 下
删除 /system/framework/uiautomator.odex

adb push D:\odex/uiautomator.jar  /sdcard/
adb shell
$su
#mount -o remount,rw /system
cp /sdcard/uiautomator.jar /system/framework/

这个单jar适合移植，但会影响速度
如果只是单机使用，建议生成odex
dexopt-wrapper 传到 手机 /system/bin/ 目录 
然后执行

chmod 755 /system/bin/dexopt-wrapper

执行

dexopt-wrapper /system/framework/uiautomator.jar /system/framework/uiautomator.odex

然后在把原来的uiautomator.jar 传到/system/framework/ 就可以了
如果原版没备份的话 把压缩进的 uiautomator.dex 删除即可
最后执行 uiautomator dump 正常
