Android market: Your device is not compatible with this item

用 apktool 1.4.1 反编译Vending.apk 3.1.3版本，遇到错误，无法插入调试信息再打包重新安装。搜索反编译后的文件查找信息：

您的设备与此商品不兼容。

smali/com/android/vending/R$string.smali:.field public static final availability_restriction_hardware:I = 0x7f080191

deli@deli-laptop:~/Desktop/a/Vending$ grep 0x7f080191 * -r
smali/com/google/android/finsky/activities/DetailsAvailabilityRestrictionViewBinder.smali: const v3, 0x7f080191

猜出大概代码:

public bind(View view, Document document, int iconWidth, int iconRightMargin, DfeToc toc) {

	TextView reason = view.findViewById(R.id.restriction_reason);
	int restriction = document.getAvailabilityRestriction();

	switch (restriction) {
	case 4:
		reason.setText(R.string.availability_restriction_hardware);
		break;
	}
}

public int getAvailabilityRestriction() {
	boolean hasAvailability = mFinskyDoc.hasAvailability();
	if (hasAvailability) {
		int restriction = mFinskyDoc.getAvailability().getRestriction();
		reutrn restriction;
	}

	return -1;
}

restriction的值是通过 setRestriction 设置，读取protobuf数据，也没弄清楚，因为无法插入调试信息。发现3.1.3版本比以前版本复杂多了。

最后发现

ro.build.fingerprint=N708，N708这个是我们的项目名，临时修改编译脚本成N708_800_600，出现下划线，导致被google过滤掉了。搞第三方ROM的，注意了，别随意修改系统参数，除非你真的明白你在干啥东东。
