在 Android 10上崩溃(布局/abc_screen_simple 第17行中的充气异常)

我的应用程序从 Android 4.3一直运行到 Android 9 Pie，但是我的应用程序不能在 Android 10(QAPI 29)上运行并且会崩溃。这是我的日志-为什么会发生这种事？

java.lang.RuntimeException: Unable to start activity
ComponentInfo{ir.mahdi.circulars/ir.mahdi.circulars.MainActivity}:
android.view.InflateException: Binary XML file line #17
in ir.mahdi.circulars:layout/abc_screen_simple: Binary XML file line #17
in ir.mahdi.circulars:layout/abc_screen_simple:
Error inflating class androidx.appcompat.widget.FitWindowsLinearLayout

这是我的 mainActivity.xml

<?xml version="1.0" encoding="utf-8"?>

You can change buildTools version and sdk version from 29 to 28

    targetSdk = 28
compileSdk = 28
buildTools = '28.0.3'

Definitively your problem is the Calligraphy library, I've got the same problem and there are 2 ways to solve it:

  1. Go back to target version 28, and wait a possible update of the Calligraphy library. 2
  2. Remove the library

About the exception:

The exception error in Calligraphy comes from the use of the reflection in the library. See the last line of this exception:

E/AndroidRuntime: FATAL EXCEPTION: main
Process: com.example, PID: 8220
android.view.InflateException: Binary XML file line #17 in com.example:layout/abc_screen_simple: Binary XML file line #17 in com.example/abc_screen_simple: Error inflating class androidx.appcompat.widget.FitWindowsLinearLayout
Caused by: android.view.InflateException: Binary XML file line #17 in com.example/abc_screen_simple: Error inflating class androidx.appcompat.widget.FitWindowsLinearLayout
Caused by: java.lang.NullPointerException: Attempt to invoke virtual method 'java.lang.Object java.lang.reflect.Field.get(java.lang.Object)' on a null object reference

Android in your documentation explain that some reflection methods (non-SDK interfaces) are restricted in the API 29 platform.

Reflection via Class.getDeclaredField() or Class.getField() --------> NoSuchFieldException thrown

Reflection via Class.getDeclaredMethod(), Class.getMethod() ----> NoSuchMethodException thrown.

Reflection via Class.getDeclaredFields(), Class.getFields() --------> Non-SDK members not in results.

Reflection via Class.getDeclaredMethods(), Class.getMethods() -> Non-SDK members not in results

Update Calligraphy to newest version to solve this problem: Link: https://github.com/InflationX/Calligraphy/issues/35

More specifically, both Calligraphy and ViewPump need to be updated:

implementation 'io.github.inflationx:calligraphy3:3.1.1'
implementation 'io.github.inflationx:viewpump:2.0.3'

Migrating from Calligraphy 2 to 3 requires some code changes; see examples in Calligraphy 3 README.

When faced with this issue, just update the calligraphy and viewpump in your app gradle to the latest version. Presently, the current version is: implementation 'io.github.inflationx:calligraphy3:3.1.1' implementation 'io.github.inflationx:viewpump:2.0.3'

if you are using calligraphy so you should migrate to calligraphy3 : https://github.com/InflationX/Calligraphy

implementation 'io.github.inflationx:calligraphy3:3.1.1'
implementation 'io.github.inflationx:viewpump:2.0.3'

Migrate from chrisjenx/Calligraphy to InflationX/Calligraphy and update Calligraphy to newest version

Please foloow this below steps.
1> First of all check build.gradle(:app) file
2> If you are using  this below library:
implementation 'uk.co.chrisjenx:calligraphy:2.3.0'
3> Update this " implementation 'uk.co.chrisjenx:calligraphy:2.3.0' " library with this below library.
implementation 'io.github.inflationx:viewpump:2.0.3'
implementation 'io.github.inflationx:calligraphy3:3.1.1'
4> In project where You use this below code :
@Override
protected void attachBaseContext(Context newBase) {
super.attachBaseContext(CalligraphyContextWrapper.wrap(newBase));
}


5> Update it with this below code:


@Override
protected void attachBaseContext(Context newBase) {
super.attachBaseContext(ViewPumpContextWrapper.wrap(newBase));
}

You need to update calligraphy version and change code according to new version

You need to change repository in dependencies from

implementation "uk.co.chrisjenx:calligraphy:$caligraphyVersion"

to

implementation 'io.github.inflationx:calligraphy3:3.1.1'
implementation 'io.github.inflationx:viewpump:2.0.3'

You need to change usage of import from

import uk.co.chrisjenx.calligraphy.CalligraphyConfig;

to

import io.github.inflationx.calligraphy3.CalligraphyConfig;

Calligraphy config from

CalligraphyConfig.initDefault(new CalligraphyConfig.Builder()
.setDefaultFontPath(getResources().getString(R.string.bariol))
.setFontAttrId(R.attr.fontPath)
.build()))
.build());

to

ViewPump.init(ViewPump.builder()
.addInterceptor(new CalligraphyInterceptor(
new CalligraphyConfig.Builder()
                            

.setDefaultFontPath(getResources().getString(R.string.bariol))
.setFontAttrId(R.attr.fontPath)
.build()))
.build());

I used font bariol you can change it to yours.

& newbase to

super.attachBaseContext(ViewPumpContextWrapper.wrap(newBase));

Update your calligraphy import in your build.gradle(:app) file with this below

implementation 'io.github.inflationx:viewpump:2.0.3'

implementation 'io.github.inflationx:calligraphy3:3.1.1'

and use ViewPumpContextWrapper instead of CalligraphyContextWrapper

This dependency implementation 'com.ice.restring:restring:1.0.0' also causes this crash if targetSdkVersion equals to 29 or higher,

so if you have this dependency (implementation 'com.ice.restring:restring:1.0.0') in your gradle you can solve this problem by removing it or using another lib that work with targetSdkVersion 29
