我的应用在运行版本7.0，7.1.1和8.0.0的设备上发生了崩溃，其中包含以下堆栈跟踪：

我在报告的行上的代码很简单：
// HomeActivity class
@Override
public void onResume() {
mPresenter.onResume();
super.onResume();
renderView();
}
// BaseActivity class
@Override
protected void onResume() {
super.onResume();
// some other code
}
我做了一些挖掘，并发现了类似的question。
由于抛出的IllegalArgumentException不包含详细消息，因此我将尝试按照建议here添加额外的日志。
同时请欣赏任何帮助！

我的项目中也遇到了同样的问题。在研究过程中，我发现，如果您尝试从Activity的static方法访问任何onResume()变量或方法，也有可能。
答案 1 :(得分：0)
catch (Exception e) {
if (!mInstrumentation.onException(r.activity, e)) {
throw new RuntimeException(
"Unable to resume activity "
+ r.intent.getComponent().toShortString()
+ ": " + e.toString(), e);
}
}
这是一个链状样本，因此请检查e.getCause（）stacktrace->直到原因为空
如果找不到它，请查看活动线程中调用try块的方法：
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;
}
}
}
您需要在以下位置搜索原因
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)
最好的镜头是此问题的答案：
rjava.lang.IllegalArgumentException on startActivity(intent,bundle animantion)
答案 2 :(得分：-1)
问题在于您的包裹。您需要找到活动，片段，视图保存包裹以保存状态的位置。会有错误的顺序。例如
@Override
protected 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;
}
@Override
protected 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];
}
};
}
所以问题可能是
中的问题 @Override
public void writeToParcel(Parcel dest, int flags) {
super.writeToParcel(dest, flags);
dest.writeString(text);
}
private SavedState(Parcel source) {
super(source);
text = source.readString();
}
当包裹源阅读的顺序不好时。
