Apktool back compilation error [How to Solve]

report errors

error: No resource identifier found for attribute 'XXX' in package 'XXX'

Solution:

Save the XML file to “ http://schemas.android.com/apk/res-auto " changed to " http://schemas.android.com/apk/lib/com.app.chasebank "

other

I directly used Android killer for back compilation. There were more than 10 errors at once. It was too troublesome to change one by one, so I simply wrote a python script:

import os
import re

file = "error.txt"

def change_content(file):
    if os.path.exists(file):
        with open(file) as f:
            content = f.read()
        if "http://schemas.android.com/apk/res-auto" in content:
            print(file+":已修复")
            content = content.replace("http://schemas.android.com/apk/res-auto","http://schemas.android.com/apk/lib/com.app.chasebank")
            with open(file,"w") as f:
                f.write(content)

with open(file,encoding='utf8') as f:
    data = f.read()

result = re.findall(">W: (.*?):\d+: error: No resource identifier found for attribute",data)
for file in result:
    change_content(file)

Copy the error to the error.txt file, and then run the script to modify the XML file directly.

Sometimes, such errors will appear in the back compilation. You may need to copy the errors again and then execute the script. That is to say, some errors are not reported because the previous errors have not been solved, and all such errors cannot be reported at one time.

How to Solve Jetpack room use error

 

When building the room, there are several small problems. Record them. Basically, it is a configuration problem:

There is a problem with the query: [SQLITE_ERROR] SQL error or missing database (no such table: simple_student)。
an error is reported during compilation and the table cannot be found
you need to set the corresponding indication in the declared entity.

//Wrong
@Entity
data class StudentEntity
//Right
@Entity(tableName = "student_table")
data class StudentEntity

Not sure how to convert a Cursor to this method’s return type (kotlinx.coroutines.flow.Flow<?extends java.util.List<com.zxf.jetpackrelated.room.liveDataOrFlow.StudentEntity>>).

When the Dao layer declares the return value as livedata, an error is reported. After a long investigation, it was found that the corresponding function was declared as a suspended function
correct use should remove the corresponding suspend modifier.

//Wrong
@Query("select * from $STUDENT_TABLE_NAME")
suspend fun obtainStudentAll(): LiveData<List<StudentEntity>>
//Right
@Query("select * from $STUDENT_TABLE_NAME")
fun obtainStudentAll(): LiveData<List<StudentEntity>>

Not sure how to convert a Cursor to this method’s return type (androidx.lifecycle.LiveData<java.util.List<com.zxf.jetpackrelated.room.liveDataOrFlow.StudentEntity>>)
Similarly, it cannot be converted to flow, and the corresponding suspend modifier is removed.

//Wrong
@Query("select * from $STUDENT_TABLE_NAME")
suspend fun obtainStudentAll(): Flow<List<StudentEntity>>
//Right
@Query("select * from $STUDENT_TABLE_NAME")
fun obtainStudentAll(): Flow<List<StudentEntity>>

If you do not need to declare the return type as livedata or flow, you can directly declare suspend.

Solution

Step 1: upgrade JDK to JDK1.8

Step 2: modify the Java of Hadoop and other services

Step 3: modify the Java of zeppelin-env.sh

Step 4: modify the JDK path in the common.sh file in the bin directory of Zeppelin (important!!!)

function check_java_version() {
//Modify JAVA PATH to: /opt/modules/jdk1.8.0_202
    java_ver_output=$("${JAVA:-/opt/modules/jdk1.8.0_202}" -version 2>&1)
    
    jvmver=$(echo "$java_ver_output" | grep '[openjdk|java] version' | awk -F'"' 'NR==1 {print $2}' | cut -d\- -f1)
    JVM_VERSION=$(echo "$jvmver"|sed -e 's|^\([0-9][0-9]*\)\..*$|\1|')
    if [ "$JVM_VERSION" = "1" ]; then
        JVM_VERSION=$(echo "$jvmver"|sed -e 's|^1\.\([0-9][0-9]*\)\..*$|\1|')
    fi

    if [ "$JVM_VERSION" -lt 8 ] || { [ "$JVM_VERSION" -eq 8 ] && [ "${jvmver#*_}" -lt 151 ]; } ; then
        echo "Apache Zeppelin requires either Java 8 update 151 or newer"
        exit 1;
    fi
}

[Solved] Unity Error: ‘BuildPipeline‘ does not contain a definition for ‘GetBuildTargetName‘

@[TOC] (error: Library \ packagecache \ com. Unity. XR [email protected] \Editor\XRGeneralBuildProcessor.cs(83,52): error CS0117: ‘BuildPipeline’ does not contain a definition for ‘GetBuildTargetName’)

Problem Description:

when unity develops oculus quest, it will report an error library \ packagecache \ com.unity.xr [email protected] \Editor \ xrgeneralbuildprocessor.cs (83,52): error cs0117: ‘buildpipeline’ doors not contain a definition for ‘getbuildtargetname’
my unit version is 2019.4

Cause analysis:

the version of the plug-in matches the version of the unity step, resulting in </ font>

Solution:

delete ar foundation, downgrade XR plug-in management to 3.2.16, downgrade ar foundation and arkit XR plug-ins to 4.1.1, and reinstall ar foundation
record the pit encountered and it has been solved

Reason:
the error in tests may be the reason why Google has not updated it, so the whole system will not prompt an error during compilation. This error does not affect the subsequent use of
solutions:
error 1: isunlockingwithfacepossible() directly modifies the place where the method is called to false

Description:

Failed to configure a DataSource: 'url' attribute is not specified and no embedded datasource could be configured.

Reason: Failed to determine suitable jdbc url


Action:

Consider the following:
	If you want an embedded database (H2, HSQL or Derby), please put it on the classpath.
	If you have database settings to be loaded from a particular profile you may need to activate it (no profiles are currently active).


Process finished with exit code 1

Reason: Failed to configure a DataSource: ‘url’ attribute is not specified and no embedded datasource could be configured.

Solution:
There are other dependencies in pom.xml that affect

<dependency>
<groupId>org.mybatis.spring.boot</groupId>
<artifactId>mybatis-spring-boot-starter</artifactId>
<version>2.2.0</version>

[Solved] Error during composer operation in docker: insufficient memory

Background
Need to perform composer removal package operation on lumen framework.
Error message

docker composer remove Fatal error: Allowed memory size of 1610612736 bytes exhausted (tried to allocate 4096 byt

Solution:

/usr/local/bin/php -d memory_limit=-1 /usr/local/sbin/composer remove xxx

Explanation: php -d memory_limit=-1 means that the php process uses unlimited memory.
Note that both php and composer need to use absolute paths.

How to Solve “Error db.num is null” when starting Nacos

Nacos startup is divided into stand-alone or cluster. When you start in cluster mode but do not configure the data source that the cluster depends on, the error db.num is null will be reported

Solution

The operation of this paper is based on Windows environment, similar to Linux

Mode 1: single machine mode startup

startup.cmd -m standalone

Start as shown in the figure below:

standalone: independent
at this time, Nacos starts in stand-alone mode

Mode 2: start in cluster mode and configure the data source

Use the conf/nacos-mysql.sql file to initialize the database, and modify the conf/application.properties file to add MySQL support

spring.datasource.platform=mysql
db.num=1
db.url.0=jdbc:mysql://localhost:3306/nacos?characterEncoding=utf8&connectTimeout=1000&socketTimeout=3000&autoReconnect=true
db.user=root
db.password=1234

All the above configurations exist in the original configuration. You only need to modify the parameter value
after the modification is successful, start Nacos

startup.bat
