Unable to resume activity with java.lang.IllegalArgumentException on Android api >=24

            catch (Exception e) {                if (!mInstrumentation.onException(r.activity, e)) {                    throw new RuntimeException(                        "Unable to resume activity "                        + r.intent.getComponent().toShortString()                        + ": " + e.toString(), e);                }            }

it's a chained exeption so inspect e.getCause() stacktrace -> till cause will be null

if you'll not find it look at the method in activity thread which invokes try block:

try {  r.activity.onStateNotSaved();  r.activity.mFragments.noteStateNotSaved();  if (r.pendingIntents != null) {    deliverNewIntents(r, r.pendingIntents);    r.pendingIntents = null;  }  if (r.pendingResults != null) {    deliverResults(r, r.pendingResults);    r.pendingResults = null;  }  r.activity.performResume();  // If there is a pending local relaunch that was requested   // when the activity was  // paused, it will put the activity into paused state  // when it finally happens.  // Since the activity resumed before being relaunched,   // we don't want that to happen,  // so we need to clear the request to relaunch paused.  for (int i = mRelaunchingActivities.size() - 1; i >= 0; i--) {    final ActivityClientRecord relaunching =    mRelaunchingActivities.get(i);    if (relaunching.token == r.token        && relaunching.onlyLocalRequest &&        relaunching.startsNotResumed) {            relaunching.startsNotResumed = false;    } }}

you'll need to search for reason in:

• Activity.onStateNotSaved();
• Activity.mFragments.noteStateNotSaved();
• Activity.performResume();
• and final Activity.onNewIntent()

    Caused by java.lang.IllegalArgumentException        at android.os.Parcel.readException(Parcel.java:1697)        at android.os.Parcel.readException(Parcel.java:1646)        at android.app.ActivityManagerProxy.isTopOfTask (ActivityManagerNative.java:6600)        at android.app.Activity.isTopOfTask(Activity.java:6142)        at android.app.Activity.onResume(Activity.java:1331)

and best shot it's an answer for this issue:

rjava.lang.IllegalArgumentException on startActivity(intent,bundle animantion)

Problem is with you parcel. You need to find where activity, fragment, view is saving parcel to save state. There will be wrong sequence. e.g.

@Overrideprotected Parcelable onSaveInstanceState() {    Parcelable superState = super.onSaveInstanceState();    final CharSequence textFromEditText = mTextView.getText();    if (textFromEditText != null) {        SavedState savedState = new SavedState(superState);        savedState.text = textFromEditText.toString();        return savedState;    }    return superState;}@Overrideprotected void onRestoreInstanceState(Parcelable state) {    if (!(state instanceof SavedState)) {        super.onRestoreInstanceState(state);        return;    }    SavedState savedState = (SavedState) state;    super.onRestoreInstanceState(savedState.getSuperState());    if (!TextUtils.isEmpty(savedState.text)) {        mTextView.setText(savedState.text);    }}private static class SavedState extends BaseSavedState {    String text;    private SavedState(Parcelable superState) {        super(superState);    }    @Override    public void writeToParcel(Parcel dest, int flags) {        super.writeToParcel(dest, flags);        dest.writeString(text);    }    private SavedState(Parcel source) {        super(source);        text = source.readString();    }    public static final Creator<SavedState> CREATOR = new Creator<SavedState>() {        @Override        public SavedState createFromParcel(Parcel source) {            return new SavedState(source);        }        @Override        public SavedState[] newArray(int size) {            return new SavedState[size];        }    };}

so the problem could be somwhere in

    @Override    public void writeToParcel(Parcel dest, int flags) {        super.writeToParcel(dest, flags);        dest.writeString(text);    }    private SavedState(Parcel source) {        super(source);        text = source.readString();    }

when the sequance of Parcel source reading are bad.

I had also the same issue in my project. While researching I found that it might also be possible if you are trying to access any static variables or methods from your Activity's onResume() method.
