-## Android Signer Application
-
-`draft` `optional`
-
-This NIP describes a method for 2-way communication between an Android signer and any Nostr client on Android. The Android signer is an Android Application and the client can be a web client or an Android application.
-
-# Usage for Android applications
-
-The Android signer uses Intents and Content Resolvers to communicate between applications.
-
-To be able to use the Android signer in your application you should add this to your AndroidManifest.xml:
-
-```xml
-<queries>
-  <intent>
-    <action android:name="android.intent.action.VIEW" />
-    <category android:name="android.intent.category.BROWSABLE" />
-    <data android:scheme="nostrsigner" />
-  </intent>
-</queries>
-```
-
-Then you can use this function to check if there's a signer application installed:
-
-```kotlin
-fun isExternalSignerInstalled(context: Context): Boolean {
-  val intent =
-    Intent().apply {
-      action = Intent.ACTION_VIEW
-      data = Uri.parse("nostrsigner:")
-    }
-  val infos = context.packageManager.queryIntentActivities(intent, 0)
-  return infos.size > 0
-}
-```
-
-## Using Intents
-
-To get the result back from the Signer Application you should use `registerForActivityResult` or `rememberLauncherForActivityResult` in Kotlin. If you are using another framework check the documentation of your framework or a third party library to get the result.
-
-```kotlin
-val launcher = rememberLauncherForActivityResult(
-    contract = ActivityResultContracts.StartActivityForResult(),
-    onResult = { result ->
-        if (result.resultCode != Activity.RESULT_OK) {
-            Toast.makeText(
-                context,
-                "Sign request rejected",
-                Toast.LENGTH_SHORT
-            ).show()
-        } else {
-            val signature = activityResult.data?.getStringExtra("signature")
-            // Do something with signature ...
-        }
-    }
-)
-```
-
-Create the Intent using the **nostrsigner** scheme:
-
-```kotlin
-val intent = Intent(Intent.ACTION_VIEW, Uri.parse("nostrsigner:$content"))
-```
-
-Set the Signer package name:
-
-```kotlin
-intent.`package` = "com.example.signer"
-```
-
-Send the Intent:
-
-```kotlin
-launcher.launch(intent)
-```
-
-### Methods
-
-- **get_public_key**
-  - params:
-
-    ```kotlin
-    val intent = Intent(Intent.ACTION_VIEW, Uri.parse("nostrsigner:"))
-    intent.`package` = "com.example.signer"
-    intent.putExtra("type", "get_public_key")
-    // You can send some default permissions for the user to authorize for ever
-    val permissions = listOf(
-      Permission(
-          type = "sign_event",
-          kind = 22242
-      ),
-      Permission(
-          type = "nip44_decrypt"
-      )
-    )
-    intent.putExtra("permissions", permissions.toJson())
-    context.startActivity(intent)
-    ```
-  - result:
-    - If the user approved intent it will return the **npub** in the signature field
-
-      ```kotlin
-      val npub = intent.data?.getStringExtra("signature")

-    intent.putExtra("type", "sign_event")
-    // To handle results when not waiting between intents
-    intent.putExtra("id", event.id)
-    // Send the current logged in user npub

-  - result:
-    - If the user approved intent it will return the **signature** and **id** fields
-
-      ```kotlin

-      // the id you sent
-      val id = intent.data?.getStringExtra("id")
-      ```        
-
-- **decrypt_zap_event**
-  - params:
-
-    ```kotlin

-      // the id you sent
-      val id = intent.data?.getStringExtra("id")
-      ```         
-
-## Using Content Resolver
-
-To get the result back from Signer Application you should use contentResolver.query in Kotlin. If you are using another framework check the documentation of your framework or a third party library to get the result.
-
-If the user did not check the "remember my choice" option, the npub is not in Signer Application or the signer type is not recognized the `contentResolver` will return null
-
-For the SIGN_EVENT type Signer Application returns two columns "signature" and "event". The column event is the signed event json
-
-For the other types Signer Application returns the column "signature"
-
-If the user chose to always reject the event, signer application will return the column "rejected" and you should not open signer application
-

-        null,
-        null,
-        null
-    )
-    ```

-        if (result == null) return
-
-        if (result.moveToFirst()) {
-            val index = it.getColumnIndex("signature")
-            val eventJson = it.getString(index)
-        }
-      ```    
-
-# Usage for Web Applications
-
-Since web applications can't receive a result from the intent, you should add a modal to paste the signature or the event json or create a callback url.
-
-If you send the callback url parameter, Signer Application will send the result to the url.
-
-If you don't send a callback url, Signer Application will copy the result to the clipboard.
-
-You can configure the `returnType` to be **signature** or **event**.
-
-Android intents and browser urls have limitations, so if you are using the `returnType` of **event** consider using the parameter **compressionType=gzip** that will return "Signer1" + Base64 gzip encoded event json

+## Android Signer Application
+
+`draft` `optional`
+
+This NIP describes a method for 2-way communication between an Android signer and any Nostr client on Android. The Android signer is an Android Application and the client can be a web client or an Android application.
+
+# Usage for Android applications
+
+The Android signer uses Intents and Content Resolvers to communicate between applications.
+
+To be able to use the Android signer in your application you should add this to your AndroidManifest.xml:
+
+```xml
+<queries>
+  <intent>
+    <action android:name="android.intent.action.VIEW" />
+    <category android:name="android.intent.category.BROWSABLE" />
+    <data android:scheme="nostrsigner" />
+  </intent>
+</queries>
+```
+
+Then you can use this function to check if there's a signer application installed:
+
+```kotlin
+fun isExternalSignerInstalled(context: Context): Boolean {
+  val intent =
+    Intent().apply {
+      action = Intent.ACTION_VIEW
+      data = Uri.parse("nostrsigner:")
+    }
+  val infos = context.packageManager.queryIntentActivities(intent, 0)
+  return infos.size > 0
+}
+```
+
+## Using Intents
+
+To get the result back from the Signer Application you should use `registerForActivityResult` or `rememberLauncherForActivityResult` in Kotlin. If you are using another framework check the documentation of your framework or a third party library to get the result.
+
+```kotlin
+val launcher = rememberLauncherForActivityResult(
+    contract = ActivityResultContracts.StartActivityForResult(),
+    onResult = { result ->
+        if (result.resultCode != Activity.RESULT_OK) {
+            Toast.makeText(
+                context,
+                "Sign request rejected",
+                Toast.LENGTH_SHORT
+            ).show()
+        } else {
+            val signature = activityResult.data?.getStringExtra("signature")
+            // Do something with signature ...
+        }
+    }
+)
+```
+
+Create the Intent using the **nostrsigner** scheme:
+
+```kotlin
+val intent = Intent(Intent.ACTION_VIEW, Uri.parse("nostrsigner:$content"))
+```
+
+Set the Signer package name:
+
+```kotlin
+intent.`package` = "com.example.signer"
+```
+
+Send the Intent:
+
+```kotlin
+launcher.launch(intent)
+```

+
+## Using Content Resolver
+
+To get the result back from Signer Application you should use contentResolver.query in Kotlin. If you are using another framework check the documentation of your framework or a third party library to get the result.
+
+If the user did not check the "remember my choice" option, the npub is not in Signer Application or the signer type is not recognized the `contentResolver` will return null
+
+For the SIGN_EVENT type Signer Application returns two columns "signature" and "event". The column event is the signed event json
+
+For the other types Signer Application returns the column "signature"
+
+If the user chose to always reject the event, signer application will return the column "rejected" and you should not open signer application

+
+# Usage for Web Applications
+
+Since web applications can't receive a result from the intent, you should add a modal to paste the signature or the event json or create a callback url.
+
+If you send the callback url parameter, Signer Application will send the result to the url.
+
+If you don't send a callback url, Signer Application will copy the result to the clipboard.
+
+You can configure the `returnType` to be **signature** or **event**.
+
+Android intents and browser urls have limitations, so if you are using the `returnType` of **event** consider using the parameter **compressionType=gzip** that will return "Signer1" + Base64 gzip encoded event json
