By default, Android studio can not connect to the Azure devops source codes. To connect to the Azure devops, a plugins by Microsoft needs to be installed in the android studio. To install the plugin, follow the below steps:
I wanted to add a new sql user "sqluser" in Azure SQL server to access a database "sanjeeb".
Steps to create a new SQL user.
1) Connect to the Azure sql server with existing user using Microsoft SQL Server Management studio
2) Open new query window under Master database
3) Run the below script
CREATE LOGIN [sqllogin] WITH PASSWORD = 'verystrongpassword#1'
Scrollable readonly EditView in Kotlin
In the view xml file:<EditTextandroid:id="@+id/etResult" android:layout_width="match_parent" android:layout_height="343dp" android:background="@color/backgroundColor" android:backgroundTint="#00000000" android:ems="10" android:enabled="true" android:fontFamily="sans-serif-condensed" android:gravity="start|top" android:hint="@string/blankfoldermessage" android:importantForAutofill="no" android:inputType="none" android:paddingTop="2dp" android:singleLine="false" tools:targetApi="o" />
in the kotlin file (init function):
etResult.keyListener = null
this will allow the edit text to be multiline, not editable but scrollable.
the code below will set the button to clickable after 30 sec:
btnOk.isClickable=false
Timer().schedule(timerTask { btnOk.isClickable=true }, 1000*30)
the above code runs in a separate thread,
so the UI is responsive while running this code.doAsync {
// Normal code inside Async thread I=I+1If(I=100){ uiThread { tvResult.setText =”I is now 100!!”
}
} //More code If(x==0){uiThread { tvResult.setText =”there’s some problem!”
}
}}
Request user to give permission to read external storage in Android - (Kotlin)
if (ContextCompat.checkSelfPermission(this, Manifest.permission.READ_EXTERNAL_STORAGE) != PackageManager.PERMISSION_GRANTED) { // Permission is not granted // Should we show an explanation? if (ActivityCompat.shouldShowRequestPermissionRationale(this, Manifest.permission.READ_EXTERNAL_STORAGE)) { } else { // No explanation needed, we can request the permission. ActivityCompat.requestPermissions(this, arrayOf(Manifest.permission.READ_EXTERNAL_STORAGE), READ_STORAGE_CODE); } } else { // Permission has already been granted}
NOTE: READ_STORAGE_CODE is just an int constant with fix value like 1001, or 2023
and is a variable in class level.
identity column in that table by using the following code: SELECT col1, col2, col3=count(*)
INTO holdkey
FROM t1
GROUP BY col1, col2
HAVING count(*) > 1Select the duplicate rows into a holding table, eliminating duplicates in the process. For example: SELECT DISTINCT t1.* INTO holddups FROM t1, holdkey WHERE t1.col1 = holdkey.col1 AND t1.col2 = holdkey.col2
At this point, the holddups table should have unique PKs, however, this will not be the case if t1 had duplicate PKs, yet unique rows (as in the SSN example above). Verify that each key in holddups is unique, and that you do not have duplicate keys, yet unique rows. If so, you must stop here and reconcile which of the rows you wish to keep for a given duplicate key value. For example, the query: SELECT col1, col2, count(*) FROM holddups GROUP BY col1, col2 should return a count of 1 for each row. If yes, proceed to step 5 below. If no, you have duplicate keys, yet unique rows, and need to decide which rows to save. This will usually entail either discarding a row, or creating a new unique key value for this row. Take one of these two steps for each such duplicate PK in the holddups table.
Delete the duplicate rows from the original table. For example: DELETE t1 FROM t1, holdkey WHERE t1.col1 = holdkey.col1 AND t1.col2 = holdkey.col2
Put the unique rows back in the original table. For example: INSERT t1 SELECT * FROM holddups
