BadParcelableException when reading from Android bundle - android

I am getting BadParcelableException when reading a String from the bundle. This happens only on the release version of APK.
I have added these rules on proguard-rules.pro, but still getting the same error.
proguard-rules.pro
-keepnames class * implements android.os.Parcelable {
public static final ** CREATOR;
}
Stacktrace for the error:

Any help on what could be causing this error?

Resolved by adding #SerializedName annotation to the object variables.

InvocationTargetException : Could not execute method of the activity

I am new in Android and I want to put Click event on XML instead of java, and I have implemented following method on Activity class
public void onInfoClick(View v){
switch(v.getId()) {
case R.id.ivAcceptAmericanExpress:
showPopup(v, getString(R.string.apt_american_express));
break;
}
}
and in XML , I have done following code
<ImageView
android:id="#+id/ivAcceptAmericanExpress"
android:layout_width="24.286dp"
android:layout_height="24.286dp"
android:layout_centerVertical="true"
android:layout_marginLeft="10dp"
android:layout_toRightOf="#id/txtAcceptAmericanExpress"
android:src="#drawable/info_image"
android:onClick="onInfoClick" />
but when I click on Image I am getting following error

The InvocationTargetException usually points to an exception in the onClick method which you are trying to execute - in your case the onInfoClick method - you can confirm this by commenting out your case-statement and see if you still get the error. Once you have identified the problem - you can make the necessary changes to resolve the exception. You should probably surround the body of the method with a try-catch to be safe.

Released apk is showing Objectmapper exception "disable SerializationFeature.FAIL_ON_EMPTY_BEANS" for firebase database object sending

I am trying to implement firebase database to send class object to database. In debug mode, it works fine but in Signed apk , it shows the following error. Parsing data from database is okey.

My actual code was:
ClassReview classReview = new ClassReview(u_name, u_review, u_rat);
myFirebaseRef.child(m_id).push().setValue(map);
I have searched for solution then i got this and applied
ClassReview classReview = new ClassReview(u_name, u_review, u_rat);
ObjectMapper mapper = new ObjectMapper();
Map<String, Object> map = mapper.convertValue(classReview, Map.class);
myFirebaseRef.child(m_id).push().setValue(map);
But the problem remains same. This is my pro-guard rules for firebase
-keepattributes Signature
-keepattributes *Annotation*
-keep class com.firebase.** { *; }
-keep class com.google.firebase.quickstart.database.viewholder.** {

v7 support 23.0.1 crash: AppCompatButton.setBackgroundDrawable

I am experiencing this crash, with support library 23.0.1
It happens when showing a Dialog Fragment.
It verifies with both android.support.v4.app.DialogFragment and android.support.v7.app.AppCompatDialogFragment
Anyone else is experiencing this?
It always happens with release compilation (which has Proguard enabled), and only in some cases with debug compilation.
I am reporting the crash stacks for both fragment classes.

According to this your proguard setup should contain the following rules if you're using appcompat-v7:
-keep public class android.support.v7.widget.** { *; }
-keep public class android.support.v7.internal.widget.** { *; }
-keep public class android.support.v7.internal.view.menu.** { *; }
-keep public class * extends android.support.v4.view.ActionProvider {
public <init>(android.content.Context);
}
This will also save you from trouble when using SearchView and other things I imagine.

Cloudmine java.lang.NoClassDefFoundError: Failed resolution of: Lorg/slf4j/LoggerFactory;

I am trying to store some data using Cloudmine.
However, I got the error java.lang.NoClassDefFoundError: Failed resolution of: Lorg/slf4j/LoggerFactory; when I call initialize() for authorization.
I'm not running on a separate thread or something. I'm testing stuff out right now so I just have it so that when a button is clicked, it uploads some information from some EditText fields.
This is my code
public class ButtonClick implements View.OnClickListener {
private MainWindowActivity mainWindowActivity;
public ButtonClick(MainWindowActivity mainWindowActivity, Button doneBtn, Button addBtn) {
this.mainWindowActivity = mainWindowActivity;
addBtn.setEnabled(true);
addBtn.setOnClickListener(this);
}
#Override
public void onClick(View v) {
// This will initialize your credentials
// ERROR HERE
CMApiCredentials initialize = CMApiCredentials.initialize("id", "key");
SimpleCMObject location = new SimpleCMObject();
location.add("address", Runner.getAddressStr());
location.add("city", Runner.getCityStr());
location.add("state", Runner.getStateStr());
location.add("zip", Runner.getZipStr());
location.save(new ObjectModificationResponseCallback() {
public void onCompletion(ObjectModificationResponse response) {
Toast.makeText(mainWindowActivity, "Location saved: " + response.wasSuccess(), Toast.LENGTH_SHORT).show();
}
});
EditText address = (EditText) mainWindowActivity.findViewById(R.id.address);
address.setText("");
EditText city = (EditText) mainWindowActivity.findViewById(R.id.city);
city.setText("");
EditText state = (EditText) mainWindowActivity.findViewById(R.id.state);
state.setText("");
EditText zip = (EditText) mainWindowActivity.findViewById(R.id.zip);
zip.setText("");
}
}
This is the Logcat:

As I have commented, download zip file from SLF4J distribution and use as library in your project. Then, use slf4j-api-1.7.12.jar (and slf4j-android-1.7.12.jar if needed).
I had the same error and found this solution on github.
Just add the following to your grandle:
implementation 'org.slf4j:slf4j-api:1.7.25'
https://github.com/nomis/slf4j-android
I hade the same problem only on Android 5.0 - 5.1 (a real device and emulators). At that moment, I used Android Studio 2.3.3 and build tools v26.
I solved the problem turning off Instant Run that I didn't use anyway.
Steps:
go to File -> Settings -> Build, Execution, Deployment -> Instant run
Disable it (first checkbox).
