When Android studio installs and debugs APK, the compilation passes, but when debugging and installing online, it will report an error while executing: am start – N error
The ADB uninstall package name is not used
After searching for a long time, I found that the installation options in edit configuration were set to nothing before. When running, it will not automatically PM install
Change to default APK as follows
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.
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.

16:19:16 ninja failed with: exit status 1
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
error 2: the method is not rewritten ishhotspotenabling()
fakehotspotcontroller rewrites the ishhotspotenabling() method in this class
@Override

return false;

Solution:
1. Execute run * * main() with coverage;
2. Modify gradle.xml under. Idea
< GradleProjectSettings> Add a row under the label node
< option name=”delegatedBuild” value=”false” />
After saving, you can use run * * with Main() and debug * * with main()
Main error reports:
> Using multiple versions of the Android gradle plugin in the sample build is not allowed.
meaning: using multiple versions of the Android gradle plugin in the same version is not allowed.
positioning:
gradle version problem in
unit
Solution:
there is a gradle version file in the project
launchertemplate
maintemplate
find a code similar to the following
buildscript {
repositories {
mavenCentral()
google()
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:3.4.3'
**BUILD_SCRIPT_DEPS**}
If not, add
as shown in the figure
to ensure that the version numbers (3.4.3) in the two files are consistent

To package APK these days, you need to use the AAPT command to remove the old certificate file in APK, add a new certificate file again, and then sign and repackage again. It is found that when using the AAPT remove command, the error during crash – archive is toast is always reported. After a day’s comparison, it is found that it is related to the referenced com.android.tools.build: gradle: 4.1.1 and gradle-6.5-bin versions. As long as it is equal to or greater than this version, this error will be reported, which should be a bug of AAPT.
Solution:
1. The gradle plug-in is lower than these two versions. It’s unrealistic. It’s impossible not to upgrade it all the time.
2. Since APK is essentially a zip file, simply when deleting the file, open the APK package directly with the zip decompression software, manually delete the ball, and complete the remaining AAPT add command and re signature operation with the command line.
