Android Question B4A application android:requestLegacyExternalStorage="true" not work

[cambol]

Device target version level 29

If I used android:requestLegacyExternalStorage="true" , app will not start installing to device .

AddManifestText(
<uses-sdk android:minSdkVersion="4" android:targetSdkVersion="29"/>
<supports-screens android:largeScreens="true" 
    android:normalScreens="true" 
    android:smallScreens="true" 
    android:anyDensity="true"/>
<application android:requestLegacyExternalStorage="true"  >
</application>    
<uses-permission
    android:name="android.permission.WRITE_EXTERNAL_STORAGE"
    android:maxSdkVersion="29" />
)

To use external Storage you need to define the Permission with AddPermission(...) and you need to use Runtimepermissions to get this workung

uses-permission was used for older SDKs. I guess it is a Mistake to change the android:maxSdkVersion to 29

After modify , It still can not installing

AddManifestText(
<uses-sdk android:minSdkVersion="4" android:targetSdkVersion="29"/>
<supports-screens android:largeScreens="true" 
    android:normalScreens="true" 
    android:smallScreens="true" 
    android:anyDensity="true"/>
<uses-permission
    android:name="android.permission.WRITE_EXTERNAL_STORAGE"
    android:maxSdkVersion="29" />
<application android:requestLegacyExternalStorage="true"  >
</application>    
   
)
AddPermission(android.permission.WRITE_EXTERNAL_STORAGE)

After modify , It still can not installing

have you tried to remove this completely? The uses-permission...
I do not have this in actual projects

I haved remove ~ and still can not installing app ~
I think it's some problem with " android:requestLegacyExternalStorage"

 

[cambol]

if android:requestLegacyExternalStorage not work ~ I want to try set save files in file.dirinternal and copy these file out .

In target level 29 , who to copy these file out ?

 

[DonManfred]

Try it with a Real device. Guess the problem is the Emulator

You should set targetSdkVersion to 28 for now.

upload apk to google play ,and get AndroidManifest.xml more <application> error

My Code

AddManifestText(
<uses-sdk android:minSdkVersion="5" android:targetSdkVersion="28"/>
<supports-screens android:largeScreens="true" 
    android:normalScreens="true" 
    android:smallScreens="true" 
    android:anyDensity="true"/>
<application android:requestLegacyExternalStorage="true" >  
</application>
)
SetApplicationAttribute(android:icon, "@drawable/icon")
SetApplicationAttribute(android:label, "$LABEL$")
AddPermission(android.permission.WRITE_EXTERNAL_STORAGE)
CreateResourceFromFile(Macro, Themes.LightTheme)

Delete these two lines:
<application android:requestLegacyExternalStorage="true" >
</application>
