[jira] [Created] (CB-13474) Plugin with "" tag removes
XML elements
Eddy Frank created CB-13474:
-------------------------------
Summary: Plugin with "<edit-config>" tag removes XML elements
Key: CB-13474
URL: https://issues.apache.org/jira/browse/CB-13474
Project: Apache Cordova
Issue Type: Bug
Environment: - cordova v7.1.0
- android platform v6.3.0
Reporter: Eddy Frank
I have two plugins which modify the `AndroidManifest.xml` file.
The first plugin just adds an `<activity>` element.
The second plugin also adds some `<activity>` elements AND modifies the `<application>` element by adding the XML attribute `android:largeHeap="true"` via "<edit-config>" tag.
The first plugin works well. But the second plugin removes the `<activity>` element of the first plugin.
I have created two dummy plugin repos to reproduce this issue:
- https://github.com/eddyfrank/cordova-plugin-1
- https://github.com/eddyfrank/cordova-plugin-2
Repro steps:
```
cordova create PluginTestApp
cd PluginTestApp/
cordova platform add android
cordova plugin add https://github.com/eddyfrank/cordova-plugin-1
```
Content of the `platforms/android/AndroidManifest.xml` after adding `cordova-plugin-1`:
Looks good so far - the activity element `<activity android:name="com.example.plugin1.ActivityX" />` was added correctly.
```xml
<?xml version='1.0' encoding='utf-8'?>
<manifest android:hardwareAccelerated="true" android:versionCode="10000" android:versionName="1.0.0" package="com.example.plugintestapp" xmlns:android="http://schemas.android.com/apk/res/android">
<supports-screens android:anyDensity="true" android:largeScreens="true" android:normalScreens="true" android:resizeable="true" android:smallScreens="true" android:xlargeScreens="true" />
<uses-permission android:name="android.permission.INTERNET" />
<application android:hardwareAccelerated="true" android:icon="@mipmap/icon" android:label="@string/app_name" android:supportsRtl="true">
<activity android:configChanges="orientation|keyboardHidden|keyboard|screenSize|locale" android:label="@string/activity_name" android:launchMode="singleTop" android:name="MainActivity" android:theme="@android:style/Theme.DeviceDefault.NoActionBar" android:windowSoftInputMode="adjustResize">
<intent-filter android:label="@string/launcher_name">
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity android:name="com.example.plugin1.ActivityX" />
</application>
<uses-sdk android:minSdkVersion="16" android:targetSdkVersion="26" />
</manifest>
```
OK, let's add the second plugin:
```
cordova plugin add https://github.com/eddyfrank/cordova-plugin-2
```
Got following error:
```
Installing "cordova-plugin-2" for android
Failed to install 'cordova-plugin-2': Error: There was a conflict trying to modify attributes with <edit-config> in plugin cordova-plugin-2. The conflicting plugin, undefined, already modified the same attributes. The conflict must be resolved before cordova-plugin-2 can be added. You may use --force to add the plugin and overwrite the conflicting attributes.

The conflict must be resolved before cordova-plugin-2 can be added. You may use --force to add the plugin and overwrite the conflicting attributes.
```
=> Issue 1:
- Why does this error occur? There is no plugin in the project which has already modified attributes in the `<application>` element.
- The error message does not name the plugin: `The conflicting plugin, undefined, already modified the same attributes.`
Anyway, lets try to add `cordova-plugin-2` with `--force`:
```
cordova plugin rm cordova-plugin-2
cordova plugin add https://github.com/eddyfrank/cordova-plugin-2 --force
```
```
Installing "cordova-plugin-2" for android
--force is used. edit-config will overwrite conflicts if any. Conflicting plugins may not work as expected.
Adding cordova-plugin-2 to package.json
Saved plugin info for "cordova-plugin-2" to config.xml
```
Content of the `platforms/android/AndroidManifest.xml` after force adding the `cordova-plugin-2`:
```xml
<?xml version='1.0' encoding='utf-8'?>
<manifest android:hardwareAccelerated="true" android:versionCode="10000" android:versionName="1.0.0" package="com.example.plugintestapp" xmlns:android="http://schemas.android.com/apk/res/android">
<supports-screens android:anyDensity="true" android:largeScreens="true" android:normalScreens="true" android:resizeable="true" android:smallScreens="true" android:xlargeScreens="true" />
<uses-permission android:name="android.permission.INTERNET" />
<application android:hardwareAccelerated="true" android:icon="@mipmap/icon" android:label="@string/app_name" android:largeHeap="true" android:supportsRtl="true">
<activity android:configChanges="orientation|keyboardHidden|keyboard|screenSize|locale" android:label="@string/activity_name" android:launchMode="singleTop" android:name="MainActivity" android:theme="@android:style/Theme.DeviceDefault.NoActionBar" android:windowSoftInputMode="adjustResize">
<intent-filter android:label="@string/launcher_name">
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity android:name="com.example.plugin2.ActivityY" />
<activity android:name="com.example.plugin2.ActivityZ" />
</application>
<uses-sdk android:minSdkVersion="16" android:targetSdkVersion="26" />
</manifest>
```
=> Issue 2 (the actual issue):
The attribute `android:largeHeap="true"` was added correctly but the activity element `<activity android:name="com.example.plugin1.ActivityX" />` of the first plugin `cordova-plugin-1` was removed!
Without the "<edit-config>" tag in the `cordova-plugin-2` everything works fine. So it seems the merging functionality of the "<edit-config>" tag is buggy.
Tested with:
- cordova v7.1.0
- android platform v6.3.0
