Develop Reference

Have three errors relate to expecting an element and unresolved references

[related code for error in MainActivity.kt][2]
I have tried fn+option+return(Mac IOS) for import purpose, but still not working. Same as trying invalidate caches and restart. They are not working!
I just follow the lecture which is given by the professor step by step. The version for the Android studio on my macbook is 3.5.1
Looking for help.
I also met another error. Here is the code for the AndroidManifest.xml
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.assignment3muyaozhang0882423" >

<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity android:name=".MainActivity" >
</activity>
</application>
</manifest>
The error I met which is sync error:

Please check out my reply on your comment too.
Click on the error of text_layout and send the relevant code.

It is LinearLayout.LayoutParams.MATCH_PARENT
the underscore is missing between MATCH and PARENT

I am Trying to use facebook login in My app but I am getting an error that Manifest Merger faild

I am getting this Error.
Error:Execution failed for task ':app:processDebugManifest'.
Manifest merger failed : Attribute activity#com.facebook.FacebookActivity#theme value=(#android:style/Theme.Translucent.NoTitleBar) from AndroidManifest.xml:28:13-72
is also present at [com.facebook.android:facebook-common:4.35.0] AndroidManifest.xml:32:13-63 value=(#style/com_facebook_activity_theme).
Suggestion: add 'tools:replace="android:theme"' to element at AndroidManifest.xml:25:9-35:20 to override.

androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'
implementation 'com.facebook.android:facebook-android-sdk:[4,5)'
}

Solution is to revert to previous FB SDK in build.gradle:
dependencies {
// ...
compile 'com.facebook.android:facebook-android-sdk:4.15.0'
}

delete this line: android:theme="#android:style/Theme.Translucent.NoTitleBar"
AndroidManifest.xml
<meta-data android:name="com.facebook.sdk.ApplicationId"
android:value="#string/facebook_app_id"/>
<activity android:name="com.facebook.FacebookActivity"
android:configChanges=
"keyboard|keyboardHidden|screenLayout|screenSize|orientation"
android:label="#string/app_name" />
<activity
<!-- If you want the custom tabs when the facebook website is oppened -->
android:name="com.facebook.CustomTabActivity"
android:exported="true">
<intent-filter>
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.DEFAULT" />
<category android:name="android.intent.category.BROWSABLE" />
<data android:scheme="#string/fb_login_protocol_scheme" />
</intent-filter>
</activity>
You'll see that with custom tabs enabled the facebook website will open with a tab in the top and it will occupy the whole screen. Without this the website will open like a pop up and you can still see the app in the background if you look at the corners.
Or if you want to keep this line you need to add tools:replace="android:theme" in your manifest. But I see no reason to keep this line (correct me if I am wrong).
<activity android:name="com.facebook.FacebookActivity"
android:configChanges=
"keyboard|keyboardHidden|screenLayout|screenSize|orientation"
android:label="#string/app_name"
android:theme="#android:style/Theme.Translucent.NoTitleBar"
tools:replace="android:theme"/>
For facebook login guide.
ADITIONAL
An additional tip while working with facebook login, you will notice that when you added the facebook dependecie, com.android.support:appcompat-v7:... gives a warning saying that you have dependecies with different versions. You need to override this dependencie in order to get rid of this error
implementation 'com.android.support:customtabs:27.1.1'

Android app crashes when not in debugging mode

I've made a few apps in the past but none of them have had this issue. It works while debugging in Android Studio, but if I stop debugging and attempt to open the app directly from the phone (after it's already been installed from debugging) I get "[app name]" has stopped working"

I had to do it the hard way and commented out everything on MainActivity and then go through line by line uncommenting 1 line, install the apk and then open from my phone to see which line is causing the error, and it was this:
Bundle bundle = getIntent().getExtras();
if (bundle != null) {
//TODO: Open activity specified in key `click_action`
// THE CULPRIT:::Apparently you cannot have log statements in the app when not debugging?
// Because bundle.getString("click_action") works.
Log.println(Log.ASSERT, "Click Action: ", bundle.getString("click_action"));

After all, and error and testing, but nothing is still displayed on the dashboard.

What will Toast display when I use productFlavors in build.gradle?

I've created following project in Android Studio, and clicked on "Run" button in Android Studio to run the app.
In my mind, Android Studio will run the app with debug model, but what will Toast display? will it display the one of following options?
A: com.example.my.myapplication FLAVOR free
B: com.example.my.myapplication FLAVOR pro
C: info.dodata.messagecleanup FLAVOR free
D: info.dodata.messagecleanup FLAVOR pro
