复制代码 代码如下:

这是获取apk包的签名信息

private String getSign(Context context) {

PackageManager pm = context.getPackageManager();

List<PackageInfo> apps = pm.getInstalledPackages(PackageManager.GET_SIGNATURES);

Iterator<PackageInfo> iter = apps.iterator();

while(iter.hasNext()) {

PackageInfo packageinfo = iter.next();

String packageName = packageinfo.packageName;

return packageinfo.signatures[0].toCharsString();

if (packageName.equals(instance.getPackageName())) {

MediaApplication.logD(DownloadApk.class, packageinfo.signatures[0].toCharsString());

return packageinfo.signatures[0].toCharsString();

}

}

return null;

}

返回的签名信息结果为很长的一串数据
