Android Studio代码迁移问题小汇总

问题1：Duplicate class com.xxx.xxx.xxx.BuildConfig found in modules jetified-A-release-runtime 问题

> Duplicate class com.xxxdemo.xxx.xxx.BuildConfig found in modules jetified-A-release-runtime (:A-release:) and jetified-B-release-runtime (:B-release:)

Execution failed for task ':XXXdemo:checkReleaseDuplicateClasses'.
> A failure occurred while executing com.android.build.gradle.internal.tasks.CheckDuplicatesRunnable
> Duplicate class com.XXX.XXX.B.BuildConfig found in modules jetified-A-release-runtime (:A-release:) and jetified-B-release-runtime (:B-release:)

解决：

1、刚开始以为是依赖问题，实际上多重依赖问题也不大，主要可能是版本不同就容易出现上述问题，版本问题看以下文章：

2、但最终我的问题是AndroidManifest.xml文件里面指定的"package=MyPakageName"包名不小心写错跟我依赖的第三方aar库包名重名了，改名之后就OK了。

问题2：W/System.err: java.io.IOException: Cannot run program "su": error=13, Permission denied

代码：

Process p = Runtime.getRuntime().exec("su");

解决：

Process su = Runtime.getRuntime().exec("/system/bin/sh");

问题3：java.lang.RuntimeException: Can't create handler inside thread that has not called Looper.prepare()

场景：没有了aidl服务，获取数据需要延迟，线程新增定时器出现此问题。

解决：

private Handler mHandler;

mHandler = new Handler(Looper.getMainLooper());

问题4：android.util.AndroidRuntimeException: Calling startActivity() from outside of an Activity context requires the FLAG_ACTIVITY_NEW_TASK flag. Is this really what you want?

问题代码：
Intent intent = new Intent(mContext.getApplicationContext(), MyActivity.class);
mContext.startActivity(intent);

解决：

intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK );

问题5:The application could not be installed: INSTALL_FAILED_CONFLICTING_PROVIDER

解决：

更改android:authorities属性，该命名重名或者冲突了

<providerandroid:name="com.zoncare.provider.TDBProvider"android:authorities="com.sprovider"android:exported="true"android:process=":remote"/>

问题6：Manifest merger failed with multiple errors, see logs

解决：

aar与当前工程的Manifest清单文件重复注册了，删除当前工程文件注册即可。

问题7：BadTokenException: Unable to add window android.view.ViewRootImpl

悬浮窗权限：
onCreate()添加：

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
if (!Settings.canDrawOverlays(this)) {
Intent intent = new Intent(Settings.ACTION_MANAGE_OVERLAY_PERMISSION,
Uri.parse("package:" + getPackageName()));
startActivityForResult(intent, OVERLAY_PERMISSION_REQ_CODE);
}
}

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == OVERLAY_PERMISSION_REQ_CODE) {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
if (!Settings.canDrawOverlays(this)) {
// SYSTEM_ALERT_WINDOW permission not granted...
}
}
}
}

SDK版本>23即android 6.0以上系统会弹出一个提示框允许界面上有提示框显示，打开开关即可。

问题8：java.lang.IllegalArgumentException: Can only use lower 16 bits for requestCode

解决：

private static final int xxx_PERMISSION_REQ_CODE = 11;这里的赋值不能超过2的16次方值即35536。

问题9：ActivityThread: Failed to find provider info for com.xxx.xxxprovider

解决：

保证远程数据库访问Uri作者与manifast注册作者的一致性：

        <!-- 数据库远程访问 --><providerandroid:name="com.xxx.xxx.xxxService.provider.xxxDBProvider"android:authorities="com.aaa.aaa.aaaprovider"android:exported="true"android:process=":remote"tools:ignore="ExportedContentProvider"/>/*** DATABASE匹配，权值, 注意:保持与注册的作者一致性。*/public static final String AUTHORITIES = "com.aaa.aaa.aaaprovider";private static final UriMatcher MATCHER = new UriMatcher(UriMatcher.NO_MATCH);MATCHER.addURI(xxx.AUTHORITIES, xxx.xxx_PATH, BBB_ARCHIVES);/*注意: 保持与注册的作者一致性。*/private Uri mUri = null;public static final String xxx_URI = "content://" + AUTHORITIES + "/BBB_ARCHIVES";mUri = Uri.parse(xxx_URI);
