DroidPlugin 占坑太多，PacageManager调用，FAILED BINDER TRANSACTION

[SheepYoung]

如题，升级配置如下：
gradle-wrapper.properties:
distributionUrl=https://services.gradle.org/distributions/gradle-3.4.1-all.zip

build.gradle:
dependencies {
classpath 'com.android.tools.build:gradle:2.3.0'
}

原来使用配置是wrapper 2.10 build.gradle: 2.0 ，一切正常，升级后，能安装，但是运行，StrartActiviti的时候，报错：
Caused by: java.lang.RuntimeException: 没有可用的进程了

出现的机器与系统： Nexus 6p android 6.0 / 华为 M8 android.6.0 / 三星 Note 3 android 5.0

使用7.0 机器，貌似正常（华为p9 plus android 7.0)

我debug 到：

StaticProcessList.onCreate:
PackageManager pm = mHostContext.getPackageManager();
List activities = pm.queryIntentActivities(intent, PackageManager.GET_META_DATA);
for (ResolveInfo activity : activities) {
addActivityInfo(activity.activityInfo);
}

拿到的activities 为 0

[SheepYoung]

StaticProcessList.onCreate:
PackageManager pm = mHostContext.getPackageManager();
List activities = pm.queryIntentActivities(intent, PackageManager.GET_META_DATA);
有时候在调用 pm.queryIntentActivities的时候，报了异常：
android.os.DeadObjectException: Transaction failed on small parcel; remote process probably died

[SheepYoung]

经过测试分析，怀疑这个问题跟两个因素有关：
1.instant run
2.androidManifest.xml application 节点上加metadata（我们app接入了阿里百川的hotfix，需要添加metadata，刚开始，我怀疑与hotfix的hook冲突，后台我尝试将接入hotfix的代码去掉了， 依赖也去掉了，只留下metadata，结果发现还是不行，我直接注释掉metadata，一切正常）
附上hotfix接入指南：http:https://baichuan.taobao.com/docs/doc.htm?spm=a3c0d.7629140.0.0.QAJGSr&treeId=234&articleId=106531&docType=1

进一步分析，通过svn提交update to version 一个个关键提交测试， 发现接入了阿里的hotfix之后，开始出现这个问题，应该是metadata太长了（这里有一个metadata字段是ras key，单单字符串就1.9K个字符），导致远程packageManager 调用超过了1M，这个可能就是压死骆驼的最后一把稻草了，这个是根本的原因！因此我现在的解决方案是，将DroidPlugin的manifest 原来又9个进程的坑，我现在删掉了5个，暂时解决了该问题。
前面说到的， pm.queryIntentActivities(intent, PackageManager.GET_META_DATA); 有拿到0的情况，估计是机器的兼容性问题，我现在这样修改了之后，所有的机器都OK了。
重现方案很简单，就是在demo中作死的添加 metadata节点，value 的size大一点，加个上百个，然后这个就会出现：

@cmzy 这个问题点像dex 65535 一样，应用大了迟早都会遇到的，我这个方案也不是长久之计，看看有什么好的方案。

[cmzy]

这个确实是个问题，Binder传输数据不能太大，我得想办法处理下。

我也遇到的了同样问题，也通过修改坑位数量的方式暂时解决，期待大神的完备方案
