Android 14 解决打开app出现不兼容弹窗的问题

应用安装到 Android 14 上，出现如下提示

This app isn’t compatible with the latest version of Android. Check for an update or contact the app’s developer.

通过源码找原因。

提示的字符

根据字符找到 ./frameworks/base/core/res/res/values/strings.xml ，

<!-- Message displayed in dialog when app is 32 bit on a 64 bit system. [CHAR LIMIT=NONE] -->
<string name="deprecated_abi_message">This app isn\'t compatible with the latest version of Android. Check for an update or contact the app\'s developer.</string>

对应的中文 ./frameworks/base/core/res/res/values-zh-rCN/strings.xml ，

<string name="deprecated_abi_message" msgid="6820548011196218091">"此应用与最新版 Android 不兼容。请检查是否有更新，或与应用开发者联系。"</string>

DeprecatedAbiDialog

弹窗UI在 ./frameworks/base/services/core/java/com/android/server/wm/DeprecatedAbiDialog.java ，

package com.android.server.wm;import android.app.AlertDialog;
import android.content.Context;
import android.content.pm.ApplicationInfo;
import android.content.pm.PackageItemInfo;
import android.content.pm.PackageManager;
import android.view.Window;
import android.view.WindowManager;import com.android.internal.R;class DeprecatedAbiDialog extends AppWarnings.BaseDialog {DeprecatedAbiDialog(final AppWarnings manager, Context context,ApplicationInfo appInfo) {super(manager, appInfo.packageName);final PackageManager pm = context.getPackageManager();final CharSequence label = appInfo.loadSafeLabel(pm,PackageItemInfo.DEFAULT_MAX_LABEL_SIZE_PX,PackageItemInfo.SAFE_LABEL_FLAG_FIRST_LINE| PackageItemInfo.SAFE_LABEL_FLAG_TRIM);final CharSequence message = context.getString(R.string.deprecated_abi_message);final AlertDialog.Builder builder = new AlertDialog.Builder(context).setPositiveButton(R.string.ok, (dialog, which) ->manager.setPackageFlag(mPackageName, AppWarnings.FLAG_HIDE_DEPRECATED_ABI, true)).setMessage(message).setTitle(label);// Ensure the content view is prepared.mDialog = builder.create();mDialog.create();final Window window = mDialog.getWindow();window.setType(WindowManager.LayoutParams.TYPE_PHONE);// DO NOT MODIFY. Used by CTS to verify the dialog is displayed.window.getAttributes().setTitle("DeprecatedAbiDialog");}
}

AppWarnings

调用到 DeprecatedAbiDialog 的是 ./frameworks/base/services/core/java/com/android/server/wm/AppWarnings.java ，

showDeprecatedAbiDialogIfNeeded

很显然，如果设备是64位的，但是app只有32位的so库，就会出现这个弹窗。

还可以看到，可以通过调试的方法，关闭这个弹窗检测。
即 setprop debug.wm.disable_deprecated_abi_dialog true

    /*** Shows the "deprecated abi" warning, if necessary. This can only happen is the device* supports both 64-bit and 32-bit ABIs, and the app only contains 32-bit libraries. The app* cannot be installed if the device only supports 64-bit ABI while the app contains only 32-bit* libraries.** @param r activity record for which the warning may be displayed*/public void showDeprecatedAbiDialogIfNeeded(ActivityRecord r) {final boolean isUsingAbiOverride = (r.info.applicationInfo.privateFlagsExt& ApplicationInfo.PRIVATE_FLAG_EXT_CPU_OVERRIDE) != 0;if (isUsingAbiOverride) {// The abiOverride flag was specified during installation, which means that if the app// is currently running in 32-bit mode, it is intended. Do not show the warning dialog.return;}// The warning dialog can also be disabled for debugging purposefinal boolean disableDeprecatedAbiDialog = SystemProperties.getBoolean("debug.wm.disable_deprecated_abi_dialog", false);if (disableDeprecatedAbiDialog) {return;}final String appPrimaryAbi = r.info.applicationInfo.primaryCpuAbi;final String appSecondaryAbi = r.info.applicationInfo.secondaryCpuAbi;final boolean appContainsOnly32bitLibraries =(appPrimaryAbi != null && appSecondaryAbi == null && !appPrimaryAbi.contains("64"));final boolean is64BitDevice =ArrayUtils.find(Build.SUPPORTED_ABIS, abi -> abi.contains("64")) != null;if (is64BitDevice && appContainsOnly32bitLibraries) {mUiHandler.showDeprecatedAbiDialog(r);}}

showDeprecatedAbiDialogUiThread

handle 的处理，调用到 showDeprecatedAbiDialogUiThread ，

	/*** Handles messages on the system process UI thread.*/private final class UiHandler extends Handler {private static final int MSG_SHOW_UNSUPPORTED_DISPLAY_SIZE_DIALOG = 1;private static final int MSG_HIDE_UNSUPPORTED_DISPLAY_SIZE_DIALOG = 2;private static final int MSG_SHOW_UNSUPPORTED_COMPILE_SDK_DIALOG = 3;private static final int MSG_HIDE_DIALOGS_FOR_PACKAGE = 4;private static final int MSG_SHOW_DEPRECATED_TARGET_SDK_DIALOG = 5;private static final int MSG_SHOW_DEPRECATED_ABI_DIALOG = 6;public UiHandler(Looper looper) {super(looper, null, true);}@Overridepublic void handleMessage(Message msg) {switch (msg.what) {//...case MSG_SHOW_DEPRECATED_ABI_DIALOG: {final ActivityRecord ar = (ActivityRecord) msg.obj;showDeprecatedAbiDialogUiThread(ar);} break;}}//...}/*** Shows the "deprecated abi" warning for the given application.* <p>* <strong>Note:</strong> Must be called on the UI thread.** @param ar record for the activity that triggered the warning*/@UiThreadprivate void showDeprecatedAbiDialogUiThread(ActivityRecord ar) {if (mDeprecatedAbiDialog != null) {mDeprecatedAbiDialog.dismiss();mDeprecatedAbiDialog = null;}if (ar != null && !hasPackageFlag(ar.packageName, FLAG_HIDE_DEPRECATED_ABI)) {mDeprecatedAbiDialog = new DeprecatedAbiDialog(AppWarnings.this, mUiContext, ar.info.applicationInfo);mDeprecatedAbiDialog.show();}}

拓展

来都来的，顺道看到了 DeprecatedTargetSdkVersionDialog 的逻辑处理，

    /*** Shows the "deprecated target sdk" warning, if necessary.** @param r activity record for which the warning may be displayed*/public void showDeprecatedTargetDialogIfNeeded(ActivityRecord r) {if (r.info.applicationInfo.targetSdkVersion < Build.VERSION.MIN_SUPPORTED_TARGET_SDK_INT) {mUiHandler.showDeprecatedTargetDialog(r);}}/*** Shows the "deprecated target sdk version" warning for the given application.* <p>* <strong>Note:</strong> Must be called on the UI thread.** @param ar record for the activity that triggered the warning*/@UiThreadprivate void showDeprecatedTargetSdkDialogUiThread(ActivityRecord ar) {if (mDeprecatedTargetSdkVersionDialog != null) {mDeprecatedTargetSdkVersionDialog.dismiss();mDeprecatedTargetSdkVersionDialog = null;}if (ar != null && !hasPackageFlag(ar.packageName, FLAG_HIDE_DEPRECATED_SDK)) {mDeprecatedTargetSdkVersionDialog = new DeprecatedTargetSdkVersionDialog(AppWarnings.this, mUiContext, ar.info.applicationInfo);mDeprecatedTargetSdkVersionDialog.show();}}

如果 app 的 targetSdkVersion 版本低于平台支持的最小sdk版本（ro.build.version.min_supported_target_sdk），就会提示：

此应用专为旧版 Android 系统打造。它可能无法正常运行，也不包含最新的安全和隐私保护功能。请检查是否有更新，或与应用开发者联系。

对应的字符是 ./frameworks/base/core/res/res/values/strings.xml 里的 deprecated_target_sdk_message

android$ cat ./frameworks/base/core/res/res/values-zh-rCN/strings.xml | grep deprecated_target_sdk_message<string name="deprecated_target_sdk_message" msgid="5246906284426844596">"此应用专为旧版 Android 系统打造。它可能无法正常运行，也不包含最新的安全和隐私保护功能。请检查是否有更新，或与应用开发者联系。"</string>
android$

It might not work properly and doesn\'t include the latest security and privacy protections. Check for an update, or contact the app\'s developer.</string>

最终显示dialog

    /*** Shows the "deprecated abi" warning for the given application.* <p>* <strong>Note:</strong> Must be called on the UI thread.** @param ar record for the activity that triggered the warning*/@UiThreadprivate void showDeprecatedAbiDialogUiThread(ActivityRecord ar) {if (mDeprecatedAbiDialog != null) {mDeprecatedAbiDialog.dismiss();mDeprecatedAbiDialog = null;}if (ar != null && !hasPackageFlag(ar.packageName, FLAG_HIDE_DEPRECATED_ABI)) {mDeprecatedAbiDialog = new DeprecatedAbiDialog(AppWarnings.this, mUiContext, ar.info.applicationInfo);mDeprecatedAbiDialog.show();}}

解决办法

使 app 支持64位的库。

修改 app 的 build.gradle ， 添加 “arm64-v8a” ，

      externalNativeBuild {cmake {//abiFilters "armeabi-v7a"abiFilters "armeabi-v7a","arm64-v8a"cppFlags "-std=c++11 -frtti -fexceptions"arguments "-DANDROID_STL=c++_static"}}ndk {//abiFilters "armeabi-v7a"abiFilters "armeabi-v7a","arm64-v8a"stl "stlport_shared"}
