I'm trying to create a directory on my android emulator but I can't do it, I already have the permission on manifest write_storage, and I get no erros but mkdir() return false, I verify if external storage is writtable too and it is, it works on physical devices my code:
/// Cria uma nova pasta para colocar o backup
File direct = new File(Environment.getExternalStorageDirectory(),
"/Financas RW Backup");
try {
if (!direct.exists()) {
if(isExternalStorageWritable()&&isExternalStorageReadable()) {
if( direct.mkdir()) {
fachada.showMessage(ExportImportDB.this," Criado");
}else{
fachada.showMessage(ExportImportDB.this," Não Criado");
}
}
}
} catch (Exception e) {
fachada.showMessage(this, e.toString());
}
You have to options:
compileSdkVersion
and targetSdkVersion
to lower version in your build.gradle
I personally don't advice the first one. For more info check:
Hope this helps!!
