文章描述了在Android12(SDK30)更新后，系统遇到的APK签名问题，即SougouIME.apk缺少APKSignatureSchemeV2签名。解决方法是修改ApkSignatureVerifier.java文件中的getMinimumSignatureSchemeVersionForTargetSdk方法以允许V1签名。

原因

android sdk 30后不支持v1版本签名

解决方法

修改/framework/base/core/java/android/util/apk/ApkSignatureVerifier.java，中的getMinimumSignatureSchemeVersionForTargetSdk方法。

public static int getMinimumSignatureSchemeVersionForTargetSdk(int targetSdk) {
        //modify add start
        //default allow v1 signature app
        /*
        if (targetSdk >= Build.VERSION_CODES.R) {
            return SignatureSchemeVersion.SIGNING_BLOCK_V2;
        }*/
        //modify add end
        return SignatureSchemeVersion.JAR;
}

注意：预装输入法时，一定要保留LatinIME输入法。因为在开机未解锁时出于加密状态，第三方输入法未设置directBootAware="true"无法启动，导致开机锁屏输入密码时无法弹出。
